So it seems that back in the mists of time when the jquery mailing list moved to Zoho I added the equivalent forums to the mailing lists to which I had been subscribed to be on my WatchList...
All of a sudden with no warning this afternoon I've suddenly received over a dozen emails from zohodiscussions.com. So it seems that emailing things on watchlists has suddenly started working. I can't find a setting for this though.
The emails as they stand are not really terribly useful, since they don't identify what particular forum they came from. I therefore can't filter them into sensible mailboxes. Putting the forum name in the subject line would be nice. Even better would be putting a mail header in there that identifies the forum. Best still would be both.
I'm also not entirely convinced that WatchList and email subscription to a forum should be the same thing...
