im thinking of starting up a new forum using mybb can someone tell me what would be the best size in mb to go for with my new hosting co.
50 MB space and 1 GB bandwidth is more than enough. Ppl offering you unlimited this and unlimtied that are just overselling (selling something they do not have). What you should be after is a low server load and a good server connection (100 Mbps). Do you have a budget in mind? Do consider you get what you pay for.
I think about $5 min. You can find dirt cheap ones, but if you get downtime or loose your site it shouldn't really surprise you.
You shouldnt be spending more than $5 a month. I would get around 100mb space and 5gb+ bandwidth. Try to buy from the top, not from a low individual reseller.
You can find hosting for very cheap but dont go thinking that your site will be up all the time. I have sent you a PM. - Prilep
A basic hosting package should be good enough at start-up to host your forum. Look for a host who will allow you easy upgrades when you need more resources in future.
I started off my forum at knownhost.com shared hosting starting at $5 and now I am at their vps. (Texas/Cali - Double/Premium BW) They are really good company, and give super fast support and helped me out with many scripting, server tweaking etc... They even help me upgrade/update softwares if you dont feel like doing so.
