When you say site, what exactly do you mean ? While the forum is the loudest and perhaps most visible aspect of maemo.org, it's just the tip of the iceberg. Companies that you hope to see support from were the ones that made sure maemo.org is treated as a stepchild from a previous marriage and the reason why there was/is no migration path to meego.com.

I'll be blunt. If Nokia pulls the plug without notice, we're dead. Unless, as stated above, you are interested in just a forum, which can indeed continue on a donations basis. The rest of maemo.org is, however, way too big/expensive to bear without major backing.
