Students – love them or hate them, there has to be a way to make money out of them. Doesn't there? That would seem to be the thinking behind the burgeoning number of sites targeting the student community in the UK. The latest of which is StudentAd - a classified advertising service aimed at universities and further education colleges. The idea is a simple one - it replicates the noticeboard found in most college buildings. So if you want to sell your old books, or have a room available in your house, rather than write out the details on a bit of card and pin said bit of card over the top of someone else's bit of card, you can go online and advertise it on the Net. And the best part – from the students' point of view – is that it's free. All you have to do is go to the site, pick the region you want to advertise in and place your ad. Simple as that. StudentAd's MD, Gary Hector, is ready to fend off student pranksters though. "The service will filter out all swear words," he told The Register. But, as yet, there's nothing in place to weed out (if you'll excuse the pun) the sale of drugs on StudentAd. So, if you've got a couple of slabs of something fragrant under your bed and you need to expand your market... phone the police and do the right thing. According to Hector, the most popular items expected to be advertised are second hand books, vacant rooms and jobs. The service will make money by selling banner adverts, and line ads to companies wanting to target the students in their area. So far it is being promoted in around 12 regions, with a further 20 to follow later this year. The service should be capable of holding around 5000 ads per region, Hector said.
