I suppose it makes sense to keep the bugtracker centralized. Since you're using Github for your repository & forking action I suggest going with that?
Or what are the advantages of using redmine over Github issues? Most people looking at the code & contributing are probably looking at the Github issues list as well.
I know GH issues is pretty simple, but it works well for the common cases imho.
At least if you want to stick with redmine, we should somehow make sure people don't post issues in 2 places. Make a notice or something on Github (or disable it if that's possible).
