I once sent out 23 messages to guitarists, all of whom professed to wanting to play the genres I was proposing, and all of whom said they were expert or advanced.
I only got 1 message back, from someone who turned out to be late 60s (said 40 in profile) and wanted to play country , it said punk and funk in profile, so wasn't interested. Still waiting for replies from the others; good thing I wasn't holding my breath!
Still strikes me as a bit rude not to reply at all - surely not all messages go into unchecked spam folders?
