frustrated

I understand that I am a senior in college and should really think for myself, but I am so confused with this new D2L. I can't get my url to go onto the page it is assigned to, I registered for the seminar on the 25th but then couldn't find how to sign up, and there is just way too many links. One thing I do like though are the chapters to the book being on here and so I am going to start reading them, but if any of you read this let me know what you did! Thanks :)
