Is there any particular etiquette to follow when inviting people to a group, or inviting yourself to one? When using the party search window I would often whisper people to ask what they're doing (since no one uses the description field), but never really get responses.
Should you have a build ready and waiting when you look to join a group, or should you have a basic idea but then work with groupmates to customize it after the group forms?
How on earth do you self-invite yourself to a group? I've looked in the manual and all over the interface but can't figure it out.
When someone spams into general chat that they're looking for a group, how do you find them in the sea of people milling around? Do you just have to type their name into the add member field in the party window or is there some shortcut? Is there a way to tell what class/level someone is without seeing them directly?
If anyone has any other tips or general points of etiquette, please lay 'em on me. I really want to play GW with other people as much as possible, and I'm sure my chances of doing so will go up if I don't project "I AM NEWB" at every opportunity when trying to get a group... I'll wait to tell people I'm newb 'til after I've saved them with some good heals.

Thanks in advance!
