Rank tags

I hope i put this in the right spot any ways pleaese speak english with this. (do not post a bunch of crap)
I want to add player tags (rank tags) by peoples names like [owner]name
Not with the underline just put that so you would understand what i mean.
Would i have to code this or get an addon? Also my server info
