I reguarly use the unanswered topics search to see if there is any thing I can help with, anyway I notice that alot of the listings tend to be Domain Listings.

My sugestion is to remove these from the unanswered topics list if possible as you can't reply to them anyway, and it would make things easier to go through.

Very good point!

eBargain Bazaar is another forum where all topics have 0 replies.

Removing these forum 'unanswered topics' would be suitable since these even though these topics have 0 replies, they are not 'unanswered topics'.
