MyBB Community Forums

Hello,

I like to make modifications to the forum's data base straith from the myphpadmin.
In many cases I understand what exactly is the purpose of a data put some times I get stuck.
Is there some tutorial about the explanations of MySQL data inserted by the forum?

Not really. Is there anything specific you are wondering about or a specific table your are looking at? Then it would be easier to for us to focus on and help you with what you're looking for.
