Have a look at http://progit.org/book/ch8-1.html

The basic workflow:

# step 1: clone from svn
git svn clone http://svn.silverstripe.com/open/modules/gallery/trunk

# step 2: add a single change from your modified vesion

# add to staging
git add

# commit (to git, not svn)
git commit

# repeat step 2 until all changes are in

# make sure you still got the latest version from svn
git svn rebase

# output all commits as patch files (and file them as a patch ticket on open)
git format-patch

You'll notice there isnt an "git svn dcommmit" or "svn commit" step in there, for the first time we'll review changes, if thats all good we can give you commit access

Actually, if you look at the description, the DOM forum is for ImageGallery, too... at least it's supposed to be.

none yet. I am really busy right now buying a house and working a lot of over time.

I haven't had time to even run Diff on it and then try to comment on it. I had to disassemble my workstation in preparation for moving so all I have is a windows laptop for work and it's not set up for programming at all.

I wont be able to start even trying to comment my changes for 3 weeks.

Hey Tim! Hope everything went well with your house purchase, all settled in now?
When do you think you can have a look at commenting and submitting your gallery changes?
As a first step, could you just attach your current state here in the forums?

Thanks
