Recent forum modifications have an impact on e-mail notifications

Hi

Two of the recent changes have had a negative impact in my following the discussions.

One was the default ordering of posts being "Best". This does not make any sense to me, as in a discussion there is timeline, and something taken out of context may not make much sense.

I was able to solve that by editing the preferences in my profile, so I am leaving that here in case it helps.

The other one I could not solve! I receive e-mail notifications and up to a few days ago notifications about the same thread were grouped in Mail under one "Conversation". Since the new changes, even though they all have the same subject, somehow the structure of the notifications make it so they do not form a Conversation. This makes for a messier mailbox. Does anyone have any clue about this? I could not find any way to change this.

TIA
