I think developers would be more apt to help if the project was managed better. Communication between devs is limited and without proper lines of communication, it's hard for everyone to be on the same page. If a new person wants to contribute, the need to find the obscure Sourceforge URLs or the www.nexuiz.com/bugs forwarding url. The wiki is outdated and crappy, the best resource is hosted at OUNS... which as alpha complained is another obscure name. IRC communication is only helpful to some degree and mixed with the clusterfuck of wikis, forum posts, svn (again offsite) and the "tracker" that is sourceforge, it's no wonder it's hard to get / keep people interested.
Keeping everything in one place would be ideal. Redmine is a swift project management system that has per project wikis, forums, repository browser, issue/feature tracking and is very extendible.
Plugins like Ez FAQ and Question would help open up the development of the project and diffuse the tension between developers and users as well as developer vs. developers.
There is a tcl script available for eggdrops to echo issues to IRC and I can go on and on.
I've been managing projects for roughly four years and have used many different applications to assist me in this process. I've recently ported all the Nexuiz Ninjaz development to Redmine and things have already been going smoother. I'm very pleased with redmine, which is catered towards the development of software.
Perhaps I should fork this post to another thread because the shot-callers really need to see this and do something about it. As Nexuiz gets bigger, this problem of project management will only get worse.
I vote for dev.nexuiz.com
