It will be nice to see Mobile Substrate get updated sooner rather than later. It seems that reinstalling it is required from time to time. The present version is a bit buggy.
However, it IS the holidays and I read a message on Sauriks page that said naturally he (and the evad3rs) needed a little break and some family/friend time too. Don't like it but cant blame them. I've tried to donate a little but I've never been charged for a JB so it's hard to complain.
