gazpar, thank you for your post

No your questions are not rookie questions and you can ask about whatever you want to know.
As for changing the font, please follow the following steps:
1- Login to your forum admin cp
2- Expand the Styles & Templates tab that can be found on the left menu
3- Click on Style Manager
4- A page will appear with all the styles you have in your forum
5- Click on the "Go" button beside the Shams Style
6- A New page will show up, scroll down this page till you find "Tabel Header"
7- You will find an option name "Font Size" , change this font size according to your needs.
and that's it. BTW this can be done to any other style.
As for the buttons, I will design them and post them here tommorow
