When creating a signature for the forums, please make sure that it falls within the guidelines given below

Using an image

If you choose to use an image in your signature, its size must be less than 500 x 100 pixels.

Using Text

Signatures are limited to 5 lines of text; users with more than this will be requested to fix their signatures. Spaces count as a line and will take away from the 5 allowed. Text may be combined with an image as long as the image fits the rule above and there are only 5 lines of text.

Keep in mind that the forum staff will ultimately determine what is an appropriate signature
