It has been a few months coming, but we have finally released all our code into the glory of LGPL open source. The open access SVN repository is open and available for anonymous read access. If anyone wants to contribute code, please contact me with what you want to add.
The svn URL is svn://svn.projectlounge.com/open/light and I will be updating a project home page soon.
There is also going to be a simple one click install via the Instant Rails framework.
If all this code seems a little too much, you can see a hosted version at: http://www.pllite.com/projects/new to create your own project there. The access code is currently "pl124" but this will change to a captcha eventually.
The next few weeks will see a lot more development, so please if you are interested in contributing to an open source project that helps people get out of email and collaborate online about projects, please let me know.
