I'm assumng it's only the OP of a thread that sees an 'accept solution' button?  (I can't see it )  It was presumably designed for threads of the Q&A type, and not really useful here. 

Thinking about the original Q&A board  .......well that's a long, gone entity!   I 'met' some good people on there, (as well as unpleasant) but we mostly found solutions, even to unpleasantness, by ignoring that long enough until it faded away!

And on a dadrk, damp Monday, with apologies to any David Tennant or Charlotte Rampling fans......

We need more depressing tv, don't we?
