I forgot you're new, so a couple of common practices on this site. All of this stuff can be found just above this text box.
Speaking is typed in bold. ex:
"How neat is that?"
Thoughts are italicized. ex:
Wow, that's pretty neat.
(I don't think these apply in this game but I'll add them anyway) Telepathy and mind speaking, I throw it into a spoiler then bold and green it. ex:
[ +- ] Message
"Hey, whoa, I'm in your mind."
Different language, I throw it in a spoiler labeled the language I'm speaking. ex:
[ +- ] Halfling
"And now I'm speaking halfling."
OOC:
OOC is used whenever you have question out of character. Helps me differentiate whether it's the character or player asking.
There is a drop down menu that says Player, if you click that it should drop down and show your character, allowing you to post as your character. This makes it easier for me to view your character sheet during combat and makes it easier for other players to know who is talking.
