Well first off, you haven't really given a whole lot of information here. We need to know a little bit more before we can really help you. Are you going to have MySQL or an SQL database equivilent? Are you going to have PHP? How much space are you going to have? What scripting languages can you work with? Please elaborate so we can give you more specific advice on how to get your forum up and running. MySQL is probibly going to be nessessary if you are going to have loggins.
