Well done with your first Expert point gte 4289.
I note you actually joined AutoPuzzles in 2009; where have you been for the last 7 years?!
I've just stumbled across this comment more than three years on. Because only an idiot would post a reply at this point, that's exactly what I'm going to do.
First, thank you for your comment. My history with AP up to that point looked something like this:
2009: Joined (don't remember why), immediately disappeared.
2015: Dropped in to solve a particular puzzle, commented on another while here, disappeared again.
2016 Nov - 2017 Jan: Dropped in again, stayed around long enough to achieve Expert status (this puzzle was my 50th point), disappeared again immediately afterward.
And since:
2018 Sep: Dropped back in and haven't disappeared yet!
