You need to close your tags by putting a / after the [ in each section. Also, sometimes using capital letters like COLOR will make it not work.

You can go to the members list and bring up a members name and go to one of their posts. It will show you how they put any colors etc. in that they used on that post. Feel free to check any of mine you want. I don't use different fonts though. Hope this helps. This is how a closed tag looks. [/color]
