We've been using Slingshot Naked ADSL for quite some time and I've usually been able to cram everything into the after hours period.
Recently though our on peak usage has increased to the point we're actually paying more than we would be on their All You Can Eat plan.
But since the All You Can Eat plan has been discontinued, I'm unsure what to do. I've only heard horrible things about Worldnet. Does anyone know what Slingshot are doing? Is it coming back or is it as dead Big Time?
