phpBB • Free and Open Source Forum Software

I do prefer a free hosting at this stage to get all familarize with the settings before moving to a paid host. I don't mind the performance and restriction issues at the moment. Any recommendations are appreicated. Thanks.

I have a private domain, for example (mydomain.com) and I would like to use it entirely for hosting of a forum. Is there any hosting which can provide free phpBB hosting for a private top level domain name? Thank you very much.
