/updatesub and /deletesub
/updatesub and /deletesub now work. Also, I've gone through and fixed some inconsistencies in the documentation (formatting, how it's laid out, etc). Finally, I've improved the API doc diff functionality some more.
Most of the management functions are now implemented. I'm going to take a week and work on some other things and then I'll get back to the API again. Please let me know if you have any questions/suggestions.
