I figured as much. I really don't know much about any of the free hosts, just what I hear people posting here and at other sites. But I'm sure whatever else they do, probably won't support free hosting for too long.
Isn't F2S a UK-based host? If it is, it amazes me its providing free hosting. Everything I hear about UK hosting is that they charge out the wazoo compared to hosts here in the U.S. Which I'm assuming means costs of serving in the UK are much more than in the U.S.
