I'm coding a simple message board and can't decide what the best way would be to mark a message as read. Actually, the only method I can come up with at this hour is store person ID and thread ID in a cross reference table. Sure, the row size for this table would be small (3 fields max), but on a popular board that's a lot of rows. Even just 10,000 threads and 500 users would be 5 million possible rows.
Any light bulbs out there?
