I finally got fed up with the sig system that the boards have. In the text box below, the text will apear in exactly the way it would when it appears on the boards. This will allow you to make ASIC pictures etc... which are impossible with current system. Once you have finished, simply open up the user details page here and copy and paste each line where it should go.
I have also made a function to check the number of characters in your sig. Remember that it must be less than 250 or else the rest will be cut off. Also, don't forget not to have more than one space in a row as it simply get counted as one. Try using some other character. I have also included a word count function, simply for interest. I hope this helps.
