This is a personal list, of all the good free hosts that offer everything you need to set up a great website such as a forum or blog.

Well first up is 10GBFreeHost.com
They are great and fast! No ads! A big 10 out of 10

Now if you want Ads, then try out ULMB.com! But the ad is 1 simple inpage popup every 24 hours. Its worth it, because you get 500gb transfer!
I give ULMB.com a 10 out of 10

I am going to continue to keep trying, i tried about 50+ hosts, a lot of them are slow or have some sort of catch. (Pay for databases -> 110mb.com)

I currently run http://superfreehost.info - It's pretty good, nothing special though. Generic free host

I'm using 110mb.com. It's quite good as free. Lack just free database.
