The most simple "banking" commands are implemented.
These are "balance", "deposit", and "withdraw". They allow you to stash your Dinars someplace safe, where they won't be pickpocketed, and where they won't weigh you down.
Note the current implementation is extremely abstract: there's no real notion of Banks or Banking as concrete entities inside the game world. Over time we'll add a fairly rich simulation of real banks, with different competing banking organizations, multiple accounts per character, interest, loans, and all that kinda stuff.
Too bad these commands weren't listed in the command reference for "commerce". It would be helpful to us newbies to have the command reference updated instead of walking thru the bulletin board. Maybe I'm just real slow--I've never played an RPG before and it's pretty tedious going so far.
