Hi, don't want to spoil your plans or anything, but the "community poll" bit worries me a bit about this otherwise nice contest. What exactly do you have in mind?

The last contests on this forum that ended with polls were a complete desaster, because online polls can be easily manipulated (especially the forum polls). The last time people created just hundrends of new accounts to vote. Someone even wrote a script to create many accounts and vote automatically. It also doesn't really help to ask the 'community', because the big majority of people who follow this contest are participants that will just try to make their own design win.

If you want a fair vote and so the best logo for your website I recommend you to come up with another solution. I think you maybe could pick a small jury of people that don't participate and let them grade the top 3 - if you really don't want to decide alone.

I'm not even participating, but I thought I mention it, because I don't like to see those things end in drama.
