Is possible to promote your site's name?

I want to use my site name as first line

[fischermx]

Can I use

MyWebSiteName.com
Wonderfull widgets,
low prices, high quality.
wwWebmasterWorldebSiteName.com

?

The syntax checker tells me there's something wrong with the first line.

This is perfectly fine, you just have to request an exception. Usually it thinks you've misspelled something.
