Hi T. Bak,
Welcome to the Appropedia wiki. Please make yourself at home! If you need a general wiki-tutorial, see the main help page (or the more in-depth one on WikiEducator).
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 https://www.appropedia.org/User:T._Bak).
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 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.
Glad to have you here!
