As a GoE staff member I'd like to say thanks for joining, and welcome to the prop building madness!
We like to make sure that new members get all the help they need learning how to change their profile picture, post pictures, videos, etc. With that in mind please send me a message if you have any questions regarding how to do stuff around here.
How do you send me a message?
Click on my profile picture and you'll go to my profile.
Take a look a couple links under my profile picture and you'll see a "send message" link.
Click that and you'll go to your mailbox. Compose and send away.
How do you know if you have a message from a member? On any page look in the upper right column and you'll see your control panel, with a link to your Inbox and other alert types.
