I wouldn't mind having a look at the implementation although come to think of it your suggestion concerning an addon is far better for future releases of the threads software. Even with the best comments in the code we will have problems.
If you want we can discuss it a bit in private and then come up with a better design. I have already implemented a calendar solution (needs tidying up though and documenting) which could in effect be modified to work as an addon.
Damn! Why does the day have to have only 24 hours and I have to sleep 5 of them
