I'm not doing too well on the typos front today. First I misspelt "integers" as "intergers", and then, after I'd reposted that fix, I discovered that I'd written "manipulated" instead of "manipulating", which inadvertantly says something completely different to that which I had intended.

It the tension that goes with finishing something! Maybe I should sleep more?

Have fun everyone. I'm in a good mood. :-)

Jill (and please ignore any stupid typos).
