Mine is in Mambo right now, with lots of stuff, community builder, etc. How much of an effort would it take to move it to Joomla, and what would be involved?
If you are running Mambo 4.5.2, I have found that the Joomla installation is really pretty easy. There is a good tutorial at this location:
help.joomla.org/content/view/818/132/
What it basically boils down to is unzip the Joomla release, upload it to your server, and let it overwrite your existing Mambo files. All that it overwrites is the core Mambo files. Components like Community Builder stay in the same place undisturbed.
I would go to that tutorial and follow the steps. Don't forget to back up all of your files before you do anything.
