To avoid confusion, I elected to write a very brief tutorial on how to use the forums features to their full potential
Adding a signature
Adding a signature is done by adding a divider (located at the bottom of the screen) and then posting the image (located two to the left of the divider button) or text you wish to use as your signature. Unfortunately due to the restrictions of making the forum, this must be done manually. Luckily, it is not very time consuming to do.
Adding headings is simply done by highlighting the line you wish to use as a heading, and pressing the 'title' button. There are three size options.
Changing font or text colour
Unfortunately, the forum does not support changing font or colour directly. However, if you are very keen on this you may post your post as an image in as many different fonts or colours as you like. If you wish to maintain the forums background colour, its code is #464646.
Hopefully this clears up any questions you may have. See you in the 'verse.
