Thanks for pointing that out. I've managed to sort out a multi-domain hosting deal, and I've been making my own landing pages with a link to the Name Silo market site page. It's a bit of extra work, but it seems that it could be worth the effort. There is a danger that Google will penalise me for cross-linking too many domains, so I think it is important to have most of the links going one way, and not to cross-link domains for sale with each other, but to use a domains for sale listing page to give surfers offers. What structure do other sellers use?
