Charles, I opened the ticket before finding this thread - search turned up nothing useful, then I happened upon this one.

Anyhow, after reading the above, and posting my stuff, I implemented the above - pruned old inactive members and shut down who's online. Host was happy, board's back up and about a day or so later someone looked at the ticket for the first time and said "let us know if you have more problems"

As of yet, there are none, but I haven't put who's online back up either.

I think your hosts's request is rediculous personally; your board doesn't seem that large to add a meaningful dent; most likely they have issues against UBB.Classic as in a large enviroment it can give issues, but with a small board they just fear what it can become...
