[PageOneX] [dev] PageOneX server is down

[Rafael Porres Molina]

I code mostly in Perl and I have never used Ruby, so  I don't know if I
could help, but If you need my sysadmin skills for any of this, just give a
shout. This week I'm quite busy but maybe next week I could find time.

Best regards,

Rafa
