This is the first time to use moodle so I'm trying it out
Yep, just letting you know that your post works, Fatima.
Well, you have come to the right place if you want to learn a little about Moodle.
If you go to the General Forum, (this link will open in a new window) the very first post there will help guide you through what you can do if you have a problem. Also, it offers some help about who to ask and where to ask.
Every aspect of Moodle is documented, some of it really well, other parts, not as well as it could be. All the information you want to get started in Moodle is located in the Moodle Docs, a really handy repository of information and some how to do stuff.
Welcome to Moodle, Fatima, it is a fascinating journey ahead of you. Good luck.
