hmm.. weird. No # 26
ok, I'll pass the info on to Jon.

As far as keeping the numbers the same in succession all the time though, so that they're always the same... I don't know if it's possible.
The numbers will change depending on what search criteria you use or
how you have the lessons sorted. (ie, by name, date or type etc..)
Plus, the site is constantly evolving and changing. New lessons are added and old lessons might be removed, changed or updated.

Instructors might also choose to hide a lesson temporarily while they're working on it. We update the pages online, and sometimes it takes several attempts before we can proofread them and make sure they're displaying properly before making them visible to the public.
