Apart from posting and playing games? Well, the link I posted sums up all options I can think of xD;; Like, if you make good drawings, you could make an art shop and sell your art! :D Or, you could use money to buy Contribution Items and sell them for gold :)
Or, since you're a newbie, you could also go to the Charities forum and chat. They could give you some gold to get you started in the Menewsha life ;D Remember not to beg though, because begging is against the rules :o
'Ellou Cheng~! Well, have you checked the How do I earn gold? thread? There are some good options there, just look for the one you're best at. You can post [no spam or double-posting in a row!] to earn gold [the longer the posts, the more gold you get] or you could play games [there are five to choose from, no more than 500 gold a day though].
