Hello S abenhariz,
Welcome to Appropedia! If you need help, please check out the Help pages (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. Please consider putting some information about yourself on your userpage and uploading a photo as well.
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. Also, 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.
Delighted to have you here, --Steven M.
