@Hack-R, please ask that question on the main site. That isn't really a chat item, & if it were answered here, in the future, no one would ever find it & benefit from the Q & A.

@gung A couple of days ago you were talking about a certain user that might have returned after a long absence. I just noticed that the profiles seem to have been merged: it is the same person. Wow. Coming back after 4 years of never logging in and starting to post dozens of answers per day right away - that's, hmm, unusual.

@amoeba Unusual, yes; but there's a good explanation. BTW, we need energetic people to answer an increasing deficit of unanswered questions. I am happy to welcome help, even from such an unexpected quarter.
