Alright babydoll, here is the deal. First, at the top of the screen it will say your name and "message centre"... you click on those when you have something. However, the dev.thoughts thingy here doesn't register a message.
You know how to add a dev. Huzzah. If you want to look at other people's work, just start clicking. Click on me (see my icon and grey name?) and start clicking on the people in my page... and just keep digging. If you find something you like, "favorite" it, and if you found an artist you like "friend them" like you did me. That is "Deviant Watch" and you will get messages linking you to their page when they add new stuff.
Any other questions? Respond to this. It will send me a message in my message centre to let me know...
Good luck and god speed grasshopper!
