I won’t name the poster, but they are one of the most prolific over the years.
Their last time on the board was over a month ago, highly unusual. I’d sent a PM about an off board issue(long story) and then an email, and have had no response.
What, if anything, can I do, or should I be concerned. The poster may, for no explained reason, be taking a hiatus from the SDMB. But I’m worried.
