If you're broke (like me) or unemployed (lie I am from time to time), then you could always contribute in other ways :) If you don't write addons you could at least help create wiki pages for addons that don't have one yet. See the news box on the Main Page.
Don't post much.. and just really getting into ACE mods. But I've already set up a reoccuring donation (Aideenwolf). :)
I believe the only thing I perfered over the /files was the ability to view the logs with the changes. I know the script puts a text file inside the zips but it doesn't quite have the same effect as being able to see what changed what was removed what was added and at what time in a pretty little window that turtle provides.
Guess I'm just a little anal about seeing each detail that goes into changes... most of the time I learn more from looking at the changed code then from tryin to start from scratch.
If it's chosen to keep SVN dev only perhaps a high donation side option could be the ability to continue to use the SVN even if you are not a dev? Just a thought.
