### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)


`git-annex` is over all working very well for me. I am able to do some things that I've wanted to be able to do for years. I believe I have worked it out well enough that I can stop testing it and start using it for real.
