Here's the link to the sig request thread http://www.tfw2005.com/boards/requests/223021-official-im-need-new-siggy-thread-take-3-a.html Some times it takes a while, just keep asking. If you get lucky and ask real nice, you might be able to get someone like Poho to do your sig, he did mine and a whole bunch of others here that are awsome.
No prob, check out the Radicons section when you can, some really cool stuff there, and post in the "i'm new here thread" over in General Disscusion, and ask some one in the Signature thread to make you up a sig.
