I envisage around 2000 to 3000 members in the first year, around 200 to 700 active members at the most and Xenforo with addons running on a hosting service which is as following. Its a shared hosting with special features, mentioned below. Server :: Dual Quad core Xeon, but exclusive load of 10% to my site. Space :: enough GB's for me to allow users to host picture albums and have upload attachments in a thread and in their account. RAM :: 512 soft allocated and 786 hard limit.. (in MB ) Multiple MySQL db's ( I will only use 2 or 3 at the max.. ( namely WP and Xenforo ) I will be obliged with your replies, I can't afford a VPS or dedicated server now, but will shift to one by the end of this year. Thanks.
