Plugin integration with Forums!!

Hi guys!

Is there any plugin that has integration with forums? Type, vBulletin, MyBB, SimpleForums ..............
I want them to come in and have to authenticate with the forum password by typing '''/l password'''
I did a search and found umn another topic that asked the same thing, but it was closed T.T
It is online. I just want a second form of authentication! I tried using the authme, but it did not work D:

Somebody can help me??

 

Because many reasons. I'm not ashamed to admit that I used a cracked client until I bought the game.

 

They do not understand it ... hahahahaha

 

1º - Log in minecraft account
2º - Log in server (Why?)

I want a particular group forum access that server, I thought of putting whitelist, but there are many players and few people to manage. D:

 

Thank you \o/
