Cheers I0540
I was aware of the "flying club" scenario and thought I read a recent post of yours where you said a closed intranet was a "club" and hence satisfied the rules.
I think I will just advertise the spare seat. However, I did want to hint in the advert about a nominal contribution, so that the number of replies would be reduced, but if this means that the advert is illegal then I guess I can't.
Thanks
