Your user page is called User:Chuck. Every page has a discussion page as well, which is has the additional prefix "talk". So the page you are reading this comment on is the discussion page which goes with your user page, and it is called User talk:Chuck. Content pages do not have a prefix, so Turtle Sense is a content page, Talk:Turtle Sense is the discussion page about that content, User:Turtle Sense would be the user page for someone who want to be know as "Turtle Sense", and that user's talk page would be User talk:Turtle Sense.
I'm guessing you got confused and clicked on Help and since that page hasn't been written yet, you thought you were still on User:Chuck. I found your edit by clicking on Recent changes and moved it for you.
We can structure the information however we want. Tom just created the beginnings of a page for documenting Phase One. It is called Turtle Sense/Phase One. I created a page called Turtle Sense/People. They are both linked to Turtle Sense/Work. The discussion pages for all of these should be relevant to what is happening on the page. In essence the discussion pages are for the editors working on the page to make decisions about what is on the page and how it should be organized and presented. So you might add a comment like "We need to find pictures of the tower to put on this page" on the discussion page, and not on the content page.
The main page for content about the project is Turtle Sense, and any subpage for the project should start with Turtle Sense and a slash to differentiate this project from any future projects on this site.
Let me know if you have any other questions.
BTW, you can sign your name by typing four tildes "~", at the end of comments on any discussion page. Like I will do here --> The four tildes are transformed into my signature: Sam (talk) 18:55, 21 October 2013 (EDT)
