Hosting Question

This is just a question for the future. If you run on one server how many members can you have with good performance. Also what hosting Companies provide clustering if needed. I doubt we ever reach that point but, it's good to have goals. We have our goals high LOL.

That's a loaded question, as it depends on the type of server:  Shared, VPS, Dedicated.  Memory on the server, Hard Drive Space and how many drives are in the server.

As far as Clustering goes, HFW does offer cluster, beyond that I don't know who else offers it.
