Hi! I will see if I can help with your questions.
Under About Me, do you have an About Me page on Ebay? If so, you can add a link here directly to that page and/or just tell a little about yourself. That is what I did on mine.
Also under Contact me, you can set up a link here so you are not giving out your email address on your listings which you do not need to do.
Here is one of my listings to give you an idea of what I wrote:
One of my current listings
The other option is that you could just leave some of the things blank. I have all my info in the payment and shipping slots so I did not use the Terms of Sale category. If you want to set up links to the different things (i.e. contact me, About Me page) you can click on the userlinks button at the top toolbar when you are working in your profiles (it is on the right hand side). Here you choose from a list of links to include in your auctions.
Hope I was able to help...if you need anything clarified or more help, just let us know!
