A lot of clans find it convenient to have a bank in the clan, where members
can deposit or withdraw gold without having to walk to the nearest town.

If you want your clan to have a clan bank, you can purchase one for 1000
credits using the 'credit buy clanbank' command.

Note that clan banks cost 1 gpt in addition to other clan dues costs.
