Heres the mail I sent to the yogscast:
I've created a Custom Map (It took 5 months to make) pretty much for you guys.
Its called Trinitology, and its a map made for TNT people like you guys
It has mazes, jumping puzzles (single player only. You're safe for now, Simon.), tnt (everywhere!) and a bunch of other stuff.
Its my dream to have you guys play it. Please consider it!
This is the reply I received a few hours later:
Thanks for sending this across to us! I'll forward it across to the
guys, but i'm unable to guarantee it will be used.
Once again, many thanks!
Wish me luck!
