I'm really happy to see Gnucleus here too! I've had some problems with the SourceForge forums.

Gnucleus is really some nice work! It really has potential to steal the show from some of the more commercial gnet programs.

I'm using it now in fact. One possible bug though: it seems to not want to push when attempting a download from some addresses. No rhyme or reason I can see - sometimes the push works, sometimes it doesn't. However once I find a "unpushable" host it stays unpushable - even if I do a new search and download or restart Gnucleus. In such cases I often have to switch to Gnotella to download the file.
