[محروم.كوم]

Hi, I have a few games fansite with more than 6000 daily users, This numbrer are increasing everyday, and I want to be prepared to 20000+ daily users.

Is time to change from a shared hosting to a Fully managed dedicated server, I dont really know if 1gb of mo/bandwidth will be prety enough.
We dont have downloads or big images, just lot of talking people.
Also if you can recomend me how many ram do I need.

Optional to help me more: If some one here have a big forum, please, tell me (aprox) how many daily users do your forum have, and the hosting name/plan, ram, montly Bandwidth do you have contract and how good it goes?
