What is on/off topic ? I've put up 3 quizzes, but one was song titles, one musical instruments, & one for St Patrick's day. I've hundreds more, but I feel they'd be far off topic for this forum.
The St Patrick one I consider like the St Pat's jokes, relevant at this time of year, as people 'gigging' this weekend may need something to waste time, either between sets, or while tuning, re-stringing, whatever.
This doesn't mean that I deplore "off topic" threads. I can choose which to read, and stop reading if I'm not interested. The "BS" thread header ('Oxen manure') does help, but I often browse those as well.
As with multi-channel TV sets, YOU retain control of the of button.
