I think it would be great if Dynadot offered a domain backorder service so that you could register domains pending delete (not just Dynadot domains). Definitely missing this when you compare Dynadot to other registrars. I look forward to seeing this soon!
I would definitely register all my domains with Dynadot if they would offer backorder (good one). As I can pay mainly by moneybookers, Dynadot is my registrar of choice anytime when I do not have funds on my cc, but only on MB (and it happens quite some time).
It would be a great feature. Hope it will work out.
