Is there a way to avoid these requests? Thanks! Hi,

How long have you been working with rails? Do you have any open source projects? Are still around Indy? Actually I now remember seeing BW3s on your twitter, so I guess so. Have you been to any of the iRug meetings? They're excellent! - Peter Boling Mack,
