The Joomla! Forge is up and ready to accept projects. VA Software has kindly donated SourceForge Enterprise Edition and 2 dual xeon servers for it to run on so this is going to give Joomla! a premiere solutions for project development. I'm sure we'll have some teething problems as things are quite a bit different from the old GForge implementation, there are some limitations that we will work diligently to overcome but I think you'll find the project management capabilities to be superb!
Check out the Joomla! Forge forum area if you have any questions.
