David B. Pritchard, author of the Encyclopedia of Chess Variant (a work which shouldn't be missed by any chess variant enthusiast) writes me:
Please feel free to give my name & address if you wish as someone who would welcome correspondence from variant inventors and researchers. There is always the possibility of a second edition of my ECV as the first edition may sell out by the end of the year.
Pritchard's address is:
Surrey GU8 4AA
