Thanks for getting this one started again Luke...always an inspiring thread.
My favourite for June - Old Friend.

I really like this "best of month". No pressure to perform. It's already done or it's too late. Just pick the best and post it. We should make a tradition.
No reason not to (unless the overhead on the mods is too great).
It needs an organiser though, Phoenix, and it sounds like you just volunteered ...
