Yes there is a trade window, and also a trade channel. On release you will not be able to make clans but that may change. There is a window that shows you how long you have played all your characters before entering a game, as well as typing /played while in a game though only for the character you are currently playing as (that second bit might not be true I can't remember and beta is down).
I will add to the noob-ish'ness, is there a character creation limit? Like, you can only have one of each class, or any sort of limitations. I know it would not really make sense to at all, just curious.
I guess you'll be able to buy more slots ^^;
but it's still better than the 5 slots of GW2...
Thanks guys! Yeah I come from a WoW background as far as 'recent' Blizz games go and had no idea how character creation would be handled in D3.
Also, quick question, if this is allowed I would like to link to a post I made earlier today (original reason for joining the forums in addition to this being where I lurk for info).
