I haven't gotten any response and I even messaged theymos to point him to this thread. It's possible that they already have all the merit sources they need for now.
You may be waiting a while,
Loycev's application was submitted January 30th and hasn't had a response. I'm not sure if anyone who applied to be a source became one or if there is any information on rejected/pending sources.
You may be correct that theymos figures there are enough, I'm guessing the idea would be to slowly introduce sources so the supply isn't flooded.
I had some time to check out your recent history and it looks like you have a few places you like to post but that you also return to the Beginners and Help section to help folks and have spread a decent amount of Merit there. They also look like posts that were deserving of Merit.
Good luck with your application
