MyBB Community Forums

I'm relativly new to websites, I have a host with which I have 2GB space and 100GB bandwidth, I know thats alot compared to most hosts, how big a forums would that be able to manage?

A fair amount actually. It's definitely enough for a start up site.

I rarely get over 200MB of traffic, I know someone else with a site which gets a load more users than mine who only uses 5GB - 15GB Month. 100GB is plenty. As for web-space, don't worry so much, MyBB is small so unless your users can upload thousands of files per post, you wont fill that up any time soon.

Thanks
