still here, and impressed with the responses, however most of them seem like major overkill...
to further clarify this, there is no requirement for a collaborative type tool
we are (locally) a very small group (4 staff) that, while functionally part of the same team, all work independently and report to management interstate. The intention here was not for a time or attendance tracking tool, rather for a simple FYI type arrangement so that we have some visibility of each others movements.
Also, operating inside a corporate LAN precludes installing a lot of software (client/server apps, databases, etc).
I've been playing around with a TiddlyWiki and have modified my original layout from a set of defined fields for each user to a single tiddler for each user which seems like an acceptable solution - yet to be put to the test though
SQL notes sounds like an interesting alternative (I've looked at this one before, albeit sometime ago, and not in this context), though again, it may be overkill.
