I do not want to clutter any of my dissertation committee member's email account with huge attachments of my dissertation drafts and reports. When I do email my chair and the rest of the committee, I will inform them that this website has been updated with the latest developments of my dissertation focusing on writing pedagogy for student engagement among first year students.
And I enjoy the idea of having all my dissertation materials being organized and in one place virtually for my chair and committee to view with (hopefully) ease. I do not care for the image of a dissertation chair/committee to look through emails or even top of their desks to find any part of a dissertation in progress. In short, I am all for organization in one place, and that is a website.
Hopefully, this website will be perceived by my chair and the committee as a good idea. We'll see how this pans out once I make progress in my dissertation.
