Sorry to hear that. I had a massive popularity drop too, partially due to a period of inactivity, and partially due to the fact that in my new apartment I don't have the space to build stuff as cool as my older MOCs.

Welcome back! What happened to your account?
Well, my old account died due to people not really commenting on it and I just decided to delete it. I went into a stage of not really building and having to work on school and the piles of homework I was getting from my classes but one day I had this urge to work on the bricks again and now I'm going to give it another try and see what I can do.
