I would have thought that very few seats would be "block up" in that way though, most people who are changing seats will be doing so at the renewal price so that means there is no reason the seats shouldn't become available as soon as people renew elsewhere.

I have changed to the family area so 4 seats have been freed in the north stand which I would hope the club put back on sale straight away.

I think Sir McManus touched on the subject last week, saying that the initial set up costs for the first trading year would be quite high. However he was quite optimistic that with the revenue streams going great that they might break even. Burgers and pints might tip us into profit!
Next year if we keep the season ticket sales might put us into a very profitable situation.
