I'm having a hard time figuring stuff out on Gaia, and the FAQs don't seem to be helping at all, so anyone reading this, please help me out!

(1)+(2) Have both been solved. =_=

(3) How do you get Gaia cash? Is the only way to pay for it with real money? 'Cause that would suck big time, especially since everything you get for the aquarium seems to be priced in cash rather than Gaia Gold. :C

(4) I don't know... I'm sure I'll run into more problems later. =_=
