Hi Steven,
I've had a look at your account entry, and it looks like the ssh keys set in
there are corrupt in some way.
Yup - I had the starts and ends of the keys, but not their middles -
there were embedded tab and space characters. :-(
I think the best next step is for you to
remove them completely and then add them back again. Please allow the hour
for cron to catch up, before trying ssh again.
Done that and it worked this time. :-)
For the record the change I made was not to try to copy and paste the
key from a terminal window to the my accounts web page, but to load the
key into firefox (via its 'open file' menu option) and then to copy and
paste it between tabs.
Cheers
Nick
