Yo everyone I'm a new member but I am too lazy to introduce myself -_- ...
But anyway here is a tutorial that improves ur sig a bit =)
And this is my first tut ever so be nice ^^;

First off pick a sig that is already done.
Here is one of mine:



1. Now first off marquee the sig by pressing ctrl+A
2. Copy the sig by pressing ctrl+C
3. Paste it by pressing ctrl+V
4. On this new layer go to Filter>gaussian blur and choose from 1,7 - 2,5 Radius. I chose 1,8.
5. Now go to the blending option and choose overlay.
Done


My outcome:



And I also used another color on the new layer just for fun.
The outcome:


Ok that was the end of the tut. I hope u liked it =)
