Best server for hosting a forum ...

[Pots]

Comparing servers from asvhost.com and hostingsource.com, which one is the best for hosting a forum?

Googling and reading several forums, including this one, I have chosen Tzulo.com dedicated server hosting.
Customer service is quick and perfect, however, for technical questions they asked me to contact technical service directly, through submitting a support ticket.

For hosting a forum I'd suggest bodHOST. No hidden fees or surprises, very reliable service.  Their goal is to provide quality infrastructure hosting in world-class data facilities, at a cost accessible to enterprises, small businesses, and end-users alike.

24/7 support, SSD Storage, free migration, & 30-day money-back

For hosting your forum you need a very secure server because nowadays visitors spam on the forum and that will big maintenance issue to the webmaster

I know from personal experience that hostingsource.com chat support is online 24/7 and I personally use it quite a lot.
It's satisfying to be able to quickly handle the technical side of hosting my site and remain focused on improving the content.
