Whoa.. to much usage of the word "noob".. so ill be refering to it as N
I believe you lose the N status when you know enough about the mac and the basics on things. play around with it, don't go for every detail and ask if its possible (unless your desperate and want it confirmed it can/'t be done.
As for restricting, i dont think it would be restricted.
I said a suggestion on the irc chat (but no one cared.. or listened...) that new members should have their posts forwarded to a super stripped (of power) trusted member (meaning, helps constantly, is helpful, has been here awhile, willing to give their time) who will read the topic post then decide if it should go through, or decline it for a certain reason like, "This has already been discussed. -Link To topic- . Please use the search function in the future before attempting to post." Or change the topic title to something appropriate (Ex, "Help, Noob on fire" to "Can't figure how to network"). etc. etc. etc.
This would clear up some usual threads.
