Lol both of you are spamming, but anyways it depends on which program you are using. there are a few ways to do it, kinda. you take a signature that you made with no fonts on it and hit jump to image ready( this is if you are using photoshop) then dupilcate the frame(a little box at the bottom right of the animation window) once and create a text layer. Then right click the text layer and make propagate frame 1 unchecked. Now type your text. Then go to your first frame, and click the 'lil eyeball type button next to the text layer. Now if you want it to fade click on the little button next to the garbage can ( it's like 5 little circles fading) then take off effect and put it to 5 frames,or whatever you wish. Now hold control and click on the 5 or how every many frames you made in the middle. Click down where it says sec and pu it to no delay. Now click the first and last frame and hit 2 seconds and hit play. Now your test should fade out.
