I have created a second BCalc as a backup to the normal one at
http://bcalc.no-ip.com, both BCalcs keep the saved calculations synchronised so saving in one BCalc allows the same saved calculation to be used in the other. This should ensure that one or the other is available at all times. I have also created a site at
http://www.thrud.co.uk which I will keep upto date with changes and other information as they happen, it also contains links to the various PA related bits I've done.
Let me know if you find any problems
Cheers Thrud
