I'm an admin in a small private group; the tags have gotten out of control, so I used Zutilo to eliminate the old tags and repopulate with a small set. I've synced these to the group library online; however, I"m afraid that when another member of the group (We all have admin privileges) syncs now, the many, many old tags will get added back to the group library online, eliminating the work I've done.

I didn't find the right solution from the Internet.
