Very useful, thanks. 

I use the access control list, a lot. The built in editor works for a small number of entries and I am sure that that is how David imagined it would be used. I wrote something more to my liking for what I am doing. In short, it sorts the list and removes redundancy's. I would like to see something like this in mercury.

hmm, can't manage to see your page. Somethin wrong?

My Server log says the website is working, maybe there is a DNS problem try http://70.77.141.230/mercury/

The original link works OK from here. Maybe there was some temporary problem somewhere inbetween.

Clever little program, by the way - if I ever need to block lots of IPs I'll be sure to use it.
