Well, if an author doesn't start or keep their own TOC updated I do them on a voluntary basis.
I update the TOCs each week, on a Thursday, which means that everything's nicely up to date for the Index Crew on Fridays. So any delay you've noticed is simply down to the fact that it hasn't been a week since the last update.
They'll be updated today, as usual.
If an author wants their TOC updated on a more regular basis than that, they're very free to do it themselves.
No rule says they can't and I'm all for anything that saves me work.
But I'm afraid that I don't have the time to do them every time time an author makes a new post or on a daily basis.
