In MB (Molecular Blue- current release) you can walk, jump, chat, collect crystals, do 2 quests, roleplay and buy decorative weapons.
I recommend waiting untill the next release, CB (Crystal Blue) arrives. That will contain a whole lot more, including combat, duelling, magic, trade, ingame merchants and simple crafting (Note: havn\'t heard anything about this recently- is it still going in??).
CB is expected to be released very soon now. We speculate that it\'ll be here by the end of the month, but as always, don\'t hold your breath.
