DJK,
There arent any limitations. Our server can handle ANY scripts. Actually we have 2 servers. Our second server is for storing/downloading files. It has 40GB of space and 3.2 Terrabytes of bandwidth available each month. So we can handle everything. And can also help sites to feature bigger/smaller files and offer them to their visitors.
Well we wont allow only Real time chats as they drain too much CPU.
Sites will have full authority over its design. They only need to show our 468x60 banner and text link anywhere that the site is hosted on StrategyInformer.com. So which ever design, as long as it looks good.
We have just started hosting fan sites so we do not have any established yet. Thats why we started searching for any potential sites.
