One reason we don`t all sit together is that we go for different price options. Personally I prefer to sit side-on rather than behind the sticks.
Also we got in before the start of the games on Sunday, and if other Giants supporters come in at different times, other clubs supporters fill up the vacant spaces.
We were side on upper tier unreserved and we could have got 2000 Giants fans around us to start with, but it filled up round about the begining of our game with various supporters from various clubs, and even 3 unattached Geordies.
I think the answer is to mail shot all Giants supporters as soon as portions of the ground are apportioned to clubs. But some might want to go for reserved seats, but my advice would be to go for unreserved, because if you go early enough just before the start of the games, there is loads of space, you can always go out and come back in again and if the bulk of the space is taken up with our fans, others would probably not bother sitting there, and you could come back in to your seats when you want and they would most likely be vacant when you come back. If not you will still be able to sit near the bulk of the Giants fans.
Wigan, Saints, Hull, and Warrington fans seem to manage it ok.
