Integrating into vBulletin

Hello community,

first of all: I'm from Germany and my English is not the best so I try to do my best to explain ya all

Most of you know that the CK Editor is now part of the new vBulletin 4.x. Because VB 4.x is really not my taste and its design so I decided to stay by VBulletin 3.8x because it's simple the best.

Reason I' asking is: Does someone know the way how to integrate the CKEditor into the VBulletin? I have the needed knowledges (HTML and PHP) a lil bit and my JS knowledges are a lil bit limited. Wish I knew how to integrate the CKEditor but I still have no clue where to start.

Thanks for reading
