Why, hello there. :)
That's alright. It is a bit of an overwhelming site when you're new.
I can help you out. :yes:
To earn gold, you post in the forums. Don't spam or be rude and don't ask for donations. I know a great charity thread that you can meet new friends and chat with them. And maybe you can earn some gifts from the owner. I'll send you a link. ^^
To add a friend, go to someone's profile, and scroll down until you find the 'befriend' button. Click it and follow the instructions on how to add the friend. It's simple. ^^
