(FORTUNE Magazine) – First, folks, let's get to something that's been bugging several thousand of you (judging by my e-mail lately): the nonworking URL mentioned in the March 6 issue, or what I have come to think of as the Case of the Vanishing Website. When I tried it a few weeks ago, www.4.50megs.com/officehome20 was the address of a site (honest! I saw it!) that offered to link people to work-at-home jobs with big companies. Since then, weirdly, it has disappeared into the ether. I'm hoping that the site's owners will get in touch to give us their new address, but in the meantime, anybody on the lookout for home employment might want to check out www.gilgordon.com/hub.htm, where telecommuting guru Gil Gordon has posted lots of shrewd tips for home workers--and links to many other useful sites that, let us hope, are not about to take a powder.

As always, the subject of how to handle constant interruptions at the office, raised by "Sam the Man" (Jan. 24), drew plenty of sympathetic comments--and a couple of good suggestions. Writes Julie from Fredericksburg, Texas: "My boss often tells the story of a great company leader he once knew who never let problems or questions come into his office except within designated times of one half-hour in the morning and another half-hour in the afternoon." If the problem didn't get addressed during one session, it would just have to wait for the next. This fellow "was adamant about controlling his environment (probably why he was so successful)." Ian Gillies, a career coach in Toronto, suggests using body language to discourage pesky co-workers: "As soon as you see the person coming, stand up and move toward them." That is, do not let yourself be trapped behind your desk. If the offender doesn't take the hint, you can always keep on walking--or as Chris from Chicago suggests, "turn your back and get suddenly too busy to hear any questions. Computer screens are handy for this. This method has saved me a lot of wasted time. I used to worry about seeming rude, but with some people, being just a little bit rude is the only way to make your point."

If the war stories you've been sending me are any guide, plenty of companies still have a long way to go toward learning to accommodate people who must care for elderly parents (Feb. 21). "Emergencies can arise at any time, including during business hours," writes a reader named Elizabeth. In struggling to take care of her critically ill father, she had to talk to doctors on the phone while at the office: "Although I was able to do this quickly and discreetly, I was reprimanded for 'too much personal phone time.' " She quit. No doubt partly to avoid driving people like her right out the door, pharmaceuticals giant Bristol-Myers Squibb has set up a program called Just in Time Care, which offers employees real help from flesh-and-blood caregivers--not just referrals--to deal with child-care and elder-care crises. Writes Stacey Gibson, who's in charge of the program: "Although we're the first company to offer this kind of backup care on a nationwide basis, we expect that more and more companies will catch on."

Many thanks to all who sent interesting observations about how to tell when it's time to change jobs (Feb. 7). "Although it is now trendy to do a lot of job-hopping, let me provide a cautionary note," says Keith. "I'm 34 and have had eight jobs so far, each of which has paid better than the last. So what's the problem? I have no pension, as I never stayed anywhere long enough to get vested. In your 20s, retirement seems so far away, or else you think you'll be a dot-com millionaire by then. Now I'm trying to save like crazy to make up for lost time." Adds Tom Jones, principal consultant for a California-based management-development firm called WORx (www.breakawaynow.com): "When clients ask me if they should stay or go, I tell them to consider whether they already have three things: the opportunity to make a positive difference; opportunities to grow and develop, both personally and professionally; and the chance to do things that others cannot or will not do." If any one of the three is missing, he says, you're probably in the wrong place.

Let's suppose you've changed jobs, um, involuntarily at some point in your career. Reader Barbara Trombetta would like to hear your story for a book she's writing on what it's like to lose a job in corporate America--how and why it happens, and how you bounce back (or don't). If you'd like to talk about it--anonymously, she assures me--here's your chance to vent. Just go to www.yerout.com and tell all.
