On another board, I had quotes in my sig, but I always wanted to put new quotes into my sig, and the sig size was restricted.
So I created a PHP script that will take a text file with a bunch of quotes and sayings, one per line, and randomly select one to display. Unfortunately, most boards do not allow php tags in a signature. So now that I have the code written to pick a random quote, I'm going to write code to have the quote placed into a small image file. Then the image file is displayed in the board's signature.
But I need cheap ass server space, enough just to put a few megs of data in.
I'll make the code available to people here when I'm done with it, if you want to use it as well.
