As someone else pointed out, asking for something in /sh, either a party shout, repairs or whatever every 10-15 seconds is annoying as hell. Makes me want to shout back "Yes I have a 7/8 party, but you're not getting an invite cause you're an annoying bastard!" but I never do, cause it's just as rude
The full conversations in /sh used to bother me immediately after servers were merged, since I definitely wasn't used to that on Palamecia, but they toned down too. Occasionally someone will post something like "Weeeeeeeeeeeeeeeeeee" in 2 lines of text length out of the blue, but I usually just roll my eyes.
I seem to ALWAYS forget past quests, chores, locations and mob names, but I never forget names of people whose shouts rub me the wrong way in /sh >_>
