There is hardly any way you can make anyone look stupid in a thread like this one, except of course for you yourself.
You announced a chop contest, you promoted it to the extent of publishing a time frame and establishing some stips, and at the end you ADDED a requirement that there be more than one entry in order for the contest to be valid. I'm not aware that stip has EVER been used, especially after the fact, to weasel out of giving the prize to the one entry you deem valid.
This makes you a welsher, a chiseler, and an attention whore who probably never intended to pay up in any case. The forum deserves better, your contest deserves shitcanning, and your cred as a promoter is now zilch.
I'm going to refer the thread to Scud and Bone to see what they think.
