There’s a good summary of portal manners over at “You yank it you tank it”, as ever it comes down to “treat other people as you wish to be treated yourself”, of course if you are an anti-social loon who likes being sworn at then “be excellent to other people” should cover it.
I shall be spending very little time on my mage for the next few weeks except when I’m slacking and actively touting for business as a taxi.
