Logop:
I am not personally aware of the potential uses of these (Mandy.org, Jeanette.org, or Angora.org) domain names, but considering that they are single word, first-name domains, they ought to hold a (lot of?) value for the Mandys', Jeanettes' and Angoras' of the world.
I am sure if you get these names in front of them, their eyes will light up. The key, however, is finding the right buyer.
Most of these names are going to be appraised way below their retail value in these kinds of
reseller-centric forums. Resellers usually factor in their own guestimated cost of marketing of these domains names (as well as their own expected markups), and therefore, usually
appraise them at a price that may seem to be way below their truel value.
And of course, who is not in this game to make some money? So take these
appraisals with a grain of salt. I bet you already know that.
BTW, I visited your site, and you do seem to have some nice names on your site. Good luck with your sales efforts...
best regards
