Chae, you can see people's join dates underneath their avatars. ^^ Granted, it might not always be accurate due to several reasons regarding servers that are beyond me, really, but still, it's a good pointer.
They're not that difficult, really. They have very firmly set rules, and as long as you keep them in your mind, it'll become natural to you with time and practice. Grammatically speaking, they can be quite simple. :)
Hello, Chaelca! I'm so glad you listened to Ahmyra and decided to join us. :D If you need anything, leave me a visitor message. ^^ Also, I really love your avatar.
