Watermarks.com will be sold via Sedo's GreatDomains event. The auction started earlier today and will end on the 28th of July, ~6 days and 18 hours left at the moment of writing. No reserve.
Must have been a temporary glitch, everything seems to be working properly at the moment of writing (btw, the Watermarks.com auction will end in approximately 2 hours and 55 minutes).
