Good to see this post and some new rules. 

My main guitar picking finger has been injured for a couple of weeks, but I'm hoping to perform and video a song for you this week. I've been looking fwd to it for a while, I ran open mics in Nottingham for well over 15yrs up until around 2014. You seem like you're really catching the spirit of it too.

I'm glad you guys are sorting out the scammers and kareoke, as I've been watching some stuff lately that does, as you say, put you off it and makes a mockery of it too. You're bang on, what you have going on here is too good to let it slide down that slope.

 Of course there are exceptions, such as the one you show above, and good beatboxers etc, but don't listen to the moaners, it's definitely a move you needed to make. There are other avenues for kareoke etc, and you want to attract musicians and musicianship, and that's the one thing that would certainly ruin it eventually, if not tidied up. 

I'll be supporting regularly, hopefully from this week assuming my finger will bend enough, it was swollen straight for a while. 

Online Open Mic........................ who'd ever have thought it eh? 

Big up!!!
