Help! Another problem from cross-posting: If the manager is doing alphabetizing of the source list with any frequency, it will become very difficult and time-consuming to synchronize cross-posts. It will not be possible to simply copy and paste a column to the master file. To avoid total chaos, I suggest the manager only alphabetize once a week, and ask a mod to temporarily lock/close the thread for an hour or so, announcing in the thread the time when it will be closed for housekeeping. This isn't a total or perfect solution, but it may help keep the job from getting too crazy. Your thoughts?
