if you had two forums connected to the same MySQL database, would it work, or would there be an error? also, would the same info show up on the two forums?
(yes you can have two database front ends connected to the same forum).
(No there wouldn't be an error -at least not to start with)
(Yes, the same info would show on both forums)
It's not a great idea though! far better to have two databases, especially since you'll have access to a database server, better to make two databases on the same server.
