Most of them were created by my members you can check out the rest here http://www.photobucket.com/albums/m474/mmorpgspot/
i love the first one Its cute and gives you the since that it was recently designed since it's theme is the olympics. Thanks for sharing
from the above 4 Logos. I think 4th one is appropriate. The Olympic one is too specific and misleading. The image should clearly show the title and small description of your website which is "For all your hacking need". Except for the 4th one, the message is not easily visible if not invisible as in the 1st one. And from the link you provided, the 17th one (named: mmorpgspotkc0.png) is very much going with the concept of your website slogan( hacking). Its dark and gloomy and the O of MMORPG is awesomely designed.The rabbit looks cool too. My 2 cents.
QFT. Also, they need a bit of work on typography. The fonts are all over the place and the text is extremely hard to read. The other effects and blends are pretty cool. Not my cup of tea, but some of 'em are pretty good.
the first thing I noticed is most of them aren't original, they are just using someone elses copyrighted artwork and putting it together in a header... you wouldn't want to do that for a website that gets bigger and attracts too much attention I think unless those artists or companies don't mind you to use their artwork
Logos... right You could consider reviewing the following things : 1) Fonts 2) Colors 3) Borders and Backgrounds. good luck
