With bigger mods at least I would imagine many mod teams are facing issues of how to know what still needs to be done and what is already done, post-it notes and memory gets you only so far, so I imagine many using some tools to help with their tasks. I did search program that would of been like a flow chart, but more dynamic like Free mind, that would run online and that would have bug tracker with it as well as todo lists and also svn/git repository for version control and easy sharing project files. Of course I found none. So I'm currently testing Freemind + Bitbucket for doing that, of course Bitbucket is for code and it is bit stretching to call .veh and .hdv etc. as code for car mods, but maybe it is enough close. (Currently we have well over 1500 files in mod, 12 vehicles with each tens of upgrades and each has completely individual parts and physics, it has become bit hard to handle all that work history in memory). So let's hear what others have attempted and what kind of success you have had?
