I'm a member of an Infiniti Q50 forum (my daily driver) that runs software similar to this but is more modern and runs like clockwork. It's NEVER down. Given the close similarity in format, I think all of the users here would find using Club Cobra on this software a 5 minute period of adjustment, it's really super similar. Perhaps rather than raising money in the blind, maybe it would be better for Brent to say "It's going to cost $XXXX to migrate the site to this new software, let's all raise the cash to do it." I'd be in on that in a heartbeat. As in all parts of life, it's always best to have a goal rather than a blind theory.
I'll put a link below to the Q50 site, not because anyone here would be interested in the content, but to show what the site looks like and how similar in function and layout it is. That site is rock stable. The software seems to be good.
