I hope you will accept my thoughts on this because, alas, I don't go to home games any more, but I was here when RTK was launched and if I can I'd like to try and help you avoid any pitfalls. RTK attracted hostility because there didn't appear to be any "warning" of its being set up, and a lot of people felt RTK were telling them how to be a supporter. This idea:
We could organise a couple of hundred of us to go to an Academy home game there to support the academy players with Banners, Flags, Scarves singing throughout no matter the score! then after the match go to a local pub and discuss idea's for a group to be organised to improve the atmosphere at Anfield.
is an excellent one because it has the virtue of making people feel included at the outset (as opposed to feeling excluded as was previously the case with some people). It also has the virtue of you all getting to know eachother gradually.
I'd suggest you float the idea across other boards - the Rattle and OTK spring immediately to mind.
And take your time. Because:
I am all for anything that will bring atmosphere and singing back to Anfield,
but I think the velvet glove will work better than a sledge hammer, lead by example and all that
and pass on some education.
is excellent advice.
A name will evolve naturally following your after match sessions the best ones usually do.
