As a new user here, I haven't seen any elitism.
However, I'm quite an "established member" on the off topic section of the Minecraft Forums (Only reason I'm still there is so I can chat and make jokes about newer members acting like 8 year olds)
And that's where my point lies.
If anyone who isn't an "established member" is to post something making fun of a lesser member, no matter the context or tone, they'll usually get a warning or infraction. However, whenever me and a few others do it the mods either overlook it, or in extremely rare cases, throw in a subtle joke themselves.
Of course, this is Minecraft Forums, so it's probably different here seeing how more than 10% of non-foreign english speaking users here have a grasp of basic grammar and spelling, as opposed to mcf.
