For the site, possibly, although with the very limited number of active members at present I can't imagine too many successful sales. I doubt it would work too well in a 4 weekly publication. I suspect the lead time from receipt of ads to magazine publication would be too long.
It wouldn't be suitable for the mag as it takes an extra few weeks to rreach the rest of the world and it would be very out of date by then (in addition to lead times) However it could be a nice addition to the digicambuyer website. I will crtianly suggest it
My only reservation is that I'm worried about the amount of spam it's going to generate - but let's try it and see how it goes. Will arrange for this to go up this week
