Hi Teresa Garrison,
Welcome to the Appropedia wiki. Please make yourself at home! If you need a general wiki-tutorial, Wikieducator has some excellent ones.
Check your preferences and be sure you verify your email address and turn on email notification if you'd like it -- you can find out when your talk page, or any page on your watchlist, is modified. You may want to upload a photo or information about yourself to your userpage (which is at http://www.appropedia.org/User:Teresa Garrison, or this link).
If you have a particular interest or project in mind, go ahead and start it! 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. You can also call, text, or email me anytime; contact information is on my user page.
Glad to have you here!
