Hi Larry - hope you enjoy being here and get a lot out of it. --Chriswaterguy 13:43, 25 April 2013 (PDT)
Check your preferences. It's a good idea to verify your email address and turn on email notification - then you'll be notified when you get a message on your talk page, or when any page on your watchlist, is modified. You may want to upload a photo or information about yourself to your userpage (which is at User:Lgreen).
If you have a particular interest or project in mind, go ahead and start it! If you have questions or suggestions, the best place to leave them is at our community discussion page, which we call the Village pump - you should get a fast response. Or, feel free to leave me a note on my talk page if you have further questions, need help finding your way around, have a cool idea for a project, or just want to chat. If you just want to know how things work here, check out Appropedia:Policies and Appropedia:FAQ. We're a relaxed and friendly bunch though, and you can also just pick things up as you go.
Glad to have you here!
