as a follower of a lower league team myself, Sphinx would be a great alternative for you lot.
at first it would be just a good light hearted no pressure afternoon, having a few beers and enjoying yourself at a match with your mates. but you would soon become involved more as games go by.
don't look at it as abandoning your club. your club has been stolen away from you. look at it as adopting a club.
as one poster wrote above, even if just 500 fans decide to watch Sphinx it would be a massive boost for them, and not just financially.
they would not think you are taking over their club, check out the message from their Chairman:
