Ok , im making a simple forum for a CMS im making , all was going sweet until i got to this bit.
Ive made user registration + login , cant post without being logged in , Categories + sub categories , but i dont know how to post the name of the person who posted it next to the post he/she posted.
Before you say :google: i have :S but to no avail.

…:google:…

I'm sure you've made some sort of mySQL and just make a table when they post calling their post count, name, etc. in one and the post in the other….
