So far they seem ok to me, but if you look closely they are about to do away with their free hosting service, so whether they will charge you or not I dont know.

Nick, the reason that you can't find places like that anymore is cause usually they dont make money. DK3, Bravenet, Freewebs, and more used to offer Absolutely Free no catches but they almost went bankrupt from this so they started charging. I think Bravenet will still go Bankrupt though, cause the only difference in between their free and their Paid subscriptions, is that you dont have their banner on their, but if you know the coding you can take it off way too easily. This is with their free programs not their actual hosting.
