I need help with making a phpBB2 forum template

[Mr. CoolFiat]

How do I create one? I am only 13.5 years old and I need some help on making a forum. It's on Forumer. I am using the Mediocre template for better style, but it still looks cheesy and bad made. I need some help, thanks for any help!
I am 13.5 years old, gifted, and I am in Gr. 8, but I have college level spelling skills, and average a gr. 9 or 10 on average skills.

Last time I checked, phpBB started focusing more on version 3.0.x while phasing out support for 2.0.x. You'll get more help if you go here.
