I used to use SVN for maintaining my repository. I did not have much problem until i realised how hard it would be to implement it on networks. So, i jumped to bazarr( bzr). Working with bzr was cool but seeing that i was running slow when your repository grew i made a change.

Now, i am with hg. Hg works without any trouble. Buy, immediately i find some strange things be sure to find me commenting about it.
