IM and some confusion

Several office colleagues have decided to choose IM through Yahoo messenger with Meebo. It is confusing to continously create account IDs and passwords; but, of course necessary. The placement of Meebo would seem to require a webpage or blog, but the relation of IM choice to Meebo is unclear. Fortunately, the more saavy collegues will probably enlighten me. Again, tricks of the trade are necessary.

It is interesting that IM can allow one to be contacted immediately. This would allow workers to work at home. Whereas, workers often ask one another questions, these could be IMd at point of need--even to a home based worker. Also, workers can contact one another from one library building to another. Interesting. With cell phones one might even be "on call" for advice during off hours (paid per call, of course).
