command help

[howzy]

So I have seen a lot of servers with !forum command, I dont know what the proper code is, ive tried many. Also there is a !autoslay command, I was wondering if I could get that for my deathrun server? Anyone know a code or addon? Also I need a !gagtimer command thingy, it is where you can gag someone for a certain amount of time then after the time is done, it auto ungags them.
