Loving this. I hate when people join Rp's and then ask me what RP is. Maybe if you group everyone's ideas together and make a page on the wiki and Roleplaying section, it'll be rather useful to the young 'uns.
Also, I don't know whether this has already been mentioned, but when two (Or maybe more) characters are having a conversation, don't but in with random rubbish and start changing the plot. If it's not your turn to speak, don't interrupt other characters conversation (This is, assuming that the characters speaking are actually speaking about something related to the RP and important), or if you're a villager in a town, for example, go find another villager and pretend to have a normal day-to-day chat, not suddenly come up and shout "OMG, ZOMBIE!".
In addition, for all you people, last time someone summoned Queen Grief they had their head severed off.
