I thinking of starting a forum website as my server is growing in numbers a bit (around 15 at most, community of around 35 currently). I want to host a forum, wiki, and main page. I am familiar with Linux based servers, so a VPS won't be foreign to me. I don't want to spend a fortune if I'm not getting a ton of traffic though. What would be the best option for me for a small server like mine and also would be ready to expand if my server gets any bigger?
