I forked a project a while back and made some changes. Some of these changes were pulled back into the original project, but some weren't.
Other people have forked my fork as they find the changes that weren't pulled into the original useful.
I now want to fork the original project again as I have some more changes that I'd like to contribute.
I don't want to delete my original fork as it has some useful stuff, but I do want to fork again for my latest changes.
Can I do this?
