Please do upload the eagle files to dropbox, and possibly some
relevant yahoo/google group, and link to them here. That would be a
very good way to keep them 'up in the ether' and make sure they don't
disappear once your website goes bust. Otherwise, your work is lost
(right now it is, with it being unreachable because your website is
down)

Bryce,
I'm talking about the links to your page in the previous message:

check for yourself, they are 404s. Or at least were - now they seem to
work on-and-off. I was getting some sort of "Parallels® H-Sphere"
error.

Cheers,
D.
