Yeah, that's nice! Though I'd replace the ! at the end with a :, and would remove the horizontal ruler (while keeping the new paragraph for the we.phorge.it link). This way it is clear that the last line is a continuation of the previous one; otherwise, it may not be immediately clear how one is supposed to "join the community".
