The avatar and sig on this site are two of the most pronounced ways to express who you are as an individual... yet, there are those that willing substitute individuality for clan-a-mation...
I've got nothing against clans and social groups and what have you... but it gets really annoying associating a particular person with a sig or an avatar only to discover that i'm dealing with a friend of theirs... why I've even lashed out at someone and later discovered that it wasn't the idiot I thought it was...
Here are just a few examples...

A standard Coat-of-Arms, but with reference to THOTA... Not sure, but it might stand for "The Horsemen Obiviously Tizzle Alphafa"? And they have that silly backwards reflection sig thing, too...

this one had some personality, but after so many people joined it takes too long to cycle thru the name and pics...

What does that mean, anyway? Don't tough the Legion?

Now I still think people should have their own personal sigs... but i don't care who you are... that is one nice looking tooch...
Well, there are many more, but this should be enough to make my point (and ruffle some feathers, too)...
So i challenge all you clanners to get creative and make your clan sigs more creative... individuality with your clan logo emblazoned in the corner perhaps... you'll think of something, i know you can do it!
