would like this too.
We had it so that topic opening posters received a notification upon the first answer nevertheless their setting, if I recall correctly
Never ever received a complaint about that
Used to have a lot of 'post and run
' posters, asking a question and in the posting something like '...email me at...
' and then their email address, like the forum is some kind of newsgroup or a bulletin board in the local supermarket where nobody else cares for the answer.
We delete those email address and tel them people can contact them using the board mail facilities, or even better, discuss matters on the board as that is where a board is for.
Since we changed the default setting in 3.0.x, we had a better user-return result and less 0-or-1 answer postings where discussions where left open because topic starter never bothered to return
People who do not want board notifications are mostly those who are computer shaggy enough to change that in the user profile, or at least go through that.
Or in other words, we want that to be in the opt-out instead of the opt-in, and the welcome-pm-on-registration extension is a good place to point this out to them. (now we do that in the welcome-email-inactive)
can't find the source of the mod anymore.
