I did submit a pull request (offer to share our updated code) to him a couple days ago, which should have sent him an email. We got no response. If he does come back, he can accept our changes (or not, if he chooses) and update xkit.info and his version of XKit.
Since we have a ton more followers now, I’d like to reiterate that what we’re doing is an accepted practice in the world of open source, GPL-licensed software (which XKit is). We have more information on this in our FAQ.
Another question we’ve gotten is why not just change the name, and the answer to that is that if Atesh does come back, he won’t have to pick through our code to change it back.
