FWIW, my personal favorite so far has been the first one by AainaA. Sophisticated, subtle, but very effective. Some of the others have been a little clichéd, and others have been a bit too upbeat, modern, street, I can't think of the word I'm looking for here, but essentially I've seen some styles better suited to a band forum, or a skateboarding forum, or something to attract teens, rather than a professional business advice/support forum. Just my humble opinions of course, it's up to Ian in the end. A lot of good work though, in all cases. Next time I need a logo, I think I'll post here before paying somebody up front for a logo sight unseen! =)
