Sandbox

Ok, joomlajive.com is currenlty under development.  It will be a site for joomla entheusiast to come and chat, get downloads, read news articles, how-to's, opinion articles, and more.  We have developed a few concept logos that are vertainly not final and all need a little work, but they are a start.  We would like to get everyone's opinion on the logos.  Which one do you like the best, why?  What would you change, why?  Thanks for your time and your input.
