Hosting a Community [closed]
Solution 1:
Have a look at setting up a community on Ning - it's free.
Solution 2:
You really need to provide more information then "Community Website"
Do you want it to be like Facebook, like YouTube? Do you want forums, pictures, profiles, a blog, a wiki?
You could likely use a hosting account with a company like GoDaddy for a low monthly fee (less then $20 a month) and the free apps they include with it (everything above) to put something together.
Solution 3:
If you have found the software that will power your community, the next thing you should focus on is content caching. Cache as much dynamic content as possible. Doing this part right, you will definitely spend less.
