Hello,
First i would like to say that i don't have experience with git / github. I'm only used (in job and in home) svn. Anyway i see a trend in open source software to put their project in github. Apparently it allows easier branching / merging, multiple ppl can create their forks, add features, fix bugs and then ask you to merge them into main branch.
So maybe it should be considered? Maybe not now, but in future.
Maybe Serge could write more? He put Ufo2000 source in github.
