Such a server would be not absolutely necessary now, but rather a convenience for future growth. This forum is currently hosted at Tuxfamily (a French free hoster for Free projects), which is very appropriate. Database, catalogue and some small scripts will also fit on there, just no uploader.
I think we agree that we don't want neither to display any ads nor a nagging "Please donate!!" button. But when a (hosting) company would pay us a server, we could show a little "hosted by..." button at the side or at the bottom of catalogue and forum, couldn't we? See for example the "hosted by ibiblio" button on http://new.linuxfocus.org
If you are fine with that, I'd first ask some companies I know personally, then we could ask some large hosters (Strato, 1&1, OVH, Free...) with a letter that I'd first post here for approval.
In the worst case, nobody accepts and we just continue to go on with some server resources that I can provide for, and maybe we find other members who own hosting or server packages that we can use.
