>Generally, I include a 'ReIndex' function in all my systems (unless there is no one I trust in the user area), and tell them to run it once a month. Depending on the requirements of the system, the reindex function may or may not give them the option to Pack or just ReIndex.

Yes, that's pretty much what I'm going to do, include it in the monthly maintenance process, at the same time data archiving, etc. is done...
