The local branch of the FBI will run a Twitter contest this week to debut the "@FBIPortland" Twitter account. To participate, follow and watch for clues today through Friday; make a list of your answers. The first person to provide the correct list of answers on Friday will win a collectible FBI Challenge Coin. Beth Anne Steele with the Portland FBI Office says they'll use the account to share valuable information. There are rules the local FBI Office has to follow about posting on twitter: They won't respond when you "Tweet" at them, and they won't re-tweet your tweets.
