For those who don't read slashdot: Those who registered domains through Register.com between 30 January 1998 and 6 March 2001 have $5.00 coming to them (in the form of a discount off of future Register.com services), as a result of a class-action settlement. I haven't read in enough detail to determine if it's $5.00 per customer or $5.00 per domain registered in that period.
