Sounds good. To make sure its easy to integrate your changes, be sure to work from the latest code in the repository, put comments around each of your changes so it is easy for me to find them and when you are finished just zip up the modified files and send them to me. I'll review the modified files for your changes and copy them into my copy possibly with small changes or edits of my own, I won't be just replacing the files with yours so the comments wrapping your changes will be needed to make it easy for me. If you add labels to the .resx file just make note of the keys and values somewhere in comments and I'll add those to my copy as well. Then I will let you know once your changes have been integrated and pushed to the repository.
I'm shooting for a new release before the end of the month so the changes would need to either be completed pretty soon or will have to wait for after this release to integrate them for the following release.
