I'm delighted to see TE moving forward. While not a coder I can certainly help test and add some admin/user documentation.
We use TE for network infrastructure projects; to include clients, contractors and other vendors in the implemantation. Recently we added open community service projects support for area non-profits (http://projects.rainmaker-ns.com)
Although in production with periodic backups etc., our instance is not heavily used yet, nor mission critical (but will be in the future). Great opportunity to test/break things on a separate server.
