Need some Social Network solutions please
 

I am looking for some social network solutions, scripts that are reliable with not much maintenence would be best.

If you have some online solutions please post, but I am just worried about using an online solutions, because if you might build a large member base...and they decide to end the service or raise your monthly fees...and your screwed. Then your members are lost.

This is for a mainstream niche project, thanks
