Personally, I'd rather it take a bit longer for a thread to open each time...than to only be able to log in every other day.
Having been through exactly this same problem with another site I help admin, I'm fully aware of the difficulties Paul C is having fixing this. And I' know there isn't really an easy answer. Heck, if it's a matter of dollars, I'd be more apt to contribute more as well...instead of limit my opportunities to enjoy the site.
My own two cents, yours may be different.
