I noticed that the forums were missing some BB codes that are commonly used on other forums. So I want to suggest you add them. I know they won't be used much but its good to have the option.

Here are my ideas:
Strike through text - [s][/s]
Tables - [table][/table]
Subscript - [sub][/sub]
Superscript - [sup][/sup]

If anyone else has any BB codes they want to suggest, they can put them here. Just make sure your suggestion is not already available:
