How should I add signatures to my profile?

[Garamonde]

After you go here, enter the text or image (using the [img][/img] tags) you want as your signature into the text box and then either use Preview or Update Signature.

You can also play around with the text formatting and stuff. Just remember that the maximum size limit for signatures is about 234 pixels tall; anything taller will be cut off automatically to prevent your post from getting stretched and taking up more space on the page.
