Aug. 17--I need your help. The Watchdog mailbox always overflows. And with the tough times we're having, the last thing people need is business or government pouncing on them for some perceived unfairness.

But every week, Watchdog can pursue only a few cases. That's where you come in.

We're asking you to help us decide which story tips are worthy candidates for Watchdog investigations.

From the list below, culled from recent letters and e-mails, choose the topic you think is most compelling or important.

Then vote at right or send a note, postmarked no later than Saturday, to Watchdog Poll, c/o Dave Lieber, Star-Telegram, P.O. Box 1870, Fort Worth, TX 76101.

When voting, please use the topic listed at the beginning of each story description.

I'll look into the top vote-getter first. Thanks for helping me better serve you.

Savings bonds disappointment: A man who purchased savings bonds for his retirement says the U.S. Treasury originally marketed them at two interest-earning rates: a flexible rate that is adjusted with the consumer price index and a fixed rate that lasts for the life of the bond. However, the rates are now zero. He has written Treasury officials to no avail and says he bets that most people don't know their savings bond investments are earning nothing.
