coursef.com is on the survey sweep, which works its way across the whole catalog rather than returning to one name on a schedule. Putting coursef.com under watch moves it to the fast lane, where DomainDrift re-checks it about every 5 minutes and signs each reading, so a change becomes a dated event within minutes instead of waiting for the sweep to come round.
Watch coursef.com Watching a domain needs a DRM3 account. The reading above stays free and public either way.Steady. No change on record for coursef.com in the last day; this reading matches the one before it. The steady record is signed like every other reading. Watch it to catch the next move the moment it lands.
