I thought I’d mention again the California Unclaimed Property Search site; I just discovered that I was owed $600 in checks that weren’t forwarded when I moved. Maybe all of you folks are better at managing your accounts receivable than I am — but in case you aren’t, you might check this site and similar sites in other states.
UPDATE: As of 8:30 PM Eastern (on Monday), we’ve made our readers nearly $2000 (based on reports from seven readers) — or at least led them to find nearly $2000 they were owed, and in my experience collecting that money hasn’t been that hard. It pays to read The Volokh Conspiracy!
