I've created Miranda IM Git Repository at Github.com !
Q: How it works ?
A: It is a one-side integration: the code is pulled from SVN automatically, with every new commit. There is a branch named miranda-im-svn: it represent current code base from SVN/trunk.
Q: What about other SVN branches with different code ?
A: There will be no more development outside trunk for Miranda IM.
Q: How i can help ?
A: Don't send pull request to miranda-im-svn branch ! You can send patches/pull request to the master branch, or continue developing on you own.
P.S. Owners/Developers of Miranda IM can take ownership of this repo anytime :-]
