Some reasons why you might wish to sign your name to pages you work on, and set up a personal page:
- If it is a discussion page, then it is hard for readers to see who was saying what, unless names are included
- If it is a good piece of writing, people may wish to know to give compliments or to check out other things you've worked on
- If there is an error or question on what you've done, it helps people find and contact you about it.
- And finally, on your personal page if you click on your name, it shows a list of links of all of "your" pages. :-)
