Um, I'm quite confused about the UBBCode.

How do you use it? I press the 'bold' 'underline' 'font' 'color' all that stuff but it doesn't show up at all. Is it a glitch on my computer or am I just doing it wrong?

Try selecting some of the text while creating a post, and then click the bold,italic,underline,ect button. Some text will be inside 2 brackets.
Example in brackets:

['i] This is some sample text. [/i] = This is some sample text.
Just remove the " ' "

Oh. I get it...I think.

I noticed, Soccer, in another post, that you didn't remove the ' in the first part of the code. For something in italics, you want this code:
With the text in between the two.

Oh, thanx u 2! I've figured it out now

thanx again, Krystal and Kasey323.ink!
