Hi,
I have begun discussing this with Wazzz, but I can give you the same details if you want.
I did read the rules, but I wasn't sure the best way to get in contact - that is, should I pm you first, or ask to join and then discuss etc.
Over at Wc3C race contest, I have my Murloc Race i submitted. I can PM you the link or map.
Also I have various techtrees I have been working on, and soon I will be releasing a map for testing in it's early stages.
