Since a few versions back the "Clean Channel User List" feature seemed to stop working.  If I set both "Remove sharing users that have been offline" and "Remove non-sharing users that have been offline" to any length of time the client just sort of removes and re-adds them without end causing the user list scrollbar to shrink and grow constantly.  The concern is I've over 3,000 users in the list now and growing that I can't get rid of.

"Also the local purge preferences are forwarded so that the remote will not send offline member sync hashes for users that would be purged anyway."

Good stuff.  Hopefully that will sort the problem - assuming I'm interpreting it right.  The peer list runs-up to over 5,000 users now.  Presumably the client will start purging once folks upgrade to v2.52 or greater?

Cheers.

Looks to be working fine now as of 2.52-a10.
