It is a market research company whose mailing list I'm on - they are doing a project for, ermmmm, a certain airline, on on-board food, and when I signed up this morning they said that they were still a few people short. I asked if they wanted me to get them a few more people and they said yes. However, in the full e-mail I received, they did say that all travel had to be completed by the end of May. To be honest I've provided the details to half a dozen people already so that, combined with the "leads" they have generated themselves, probably means that they have got enough people in any case......
