Let me know how to update everyone on the sites pending and rolled-out changes.
This happens in all such threads. Eventually the operator goes mad and/or throws things and/or stops being polite or worse.
Apart from
Mass email/PM/Post/Giant Letters all combined for each site change?
may I suggest another thing that won't work? Another thread for announcements only. You lock it so we all don't muss it up with our critiques. We can sing your praises or not on this thread here.
If you keep the whole thread really short, maybe some of us might look at it, but I don't promise.
