Hi..
I've been looking around and I found this plugin:
http://forums.alliedmods.net/showthread.php?t=7550
I am almost sure this plugin has the code I want... I just want the code to bring people with you, like you are carrying them... But I did not find out how this plugin does it...

I am not a good coder... please, someone give me a hand...
P.S.: Ahn... and I trying to do this for the specialists mod, not Natural selection...
