Thanks, Lilly.
Whether it’s 2 or 127, the message seems wrong if the actual effect is to send out each post as a separate email.
yea i’m not sure what that is about. i think it’s site-specific. on my forum it says “about a 100 per day”.
edit: figured it out. the setting: max emails per day per user determines this number.
To me, it’s fairly clear.
Send me an email for every new post (about 2 per day)
This means you’ll get an email for every new post on the forum, and there are about 2 new posts per day.
Maybe it could say:
Send me an email for every new post (there are about 2 new posts per day)
And
Send an email for every new post except my own
just means you’ll get the same as above except your own. I suppose you are expected to know how many posts you create per day.
These seem to be the strings you can change:
js.user.mailing_list_mode.individual_no_echo
Send an email for every new post except my own
js.user.mailing_list_mode.few_per_day
Send me an email for every new post (about 2 per day)
js.user.mailing_list_mode.many_per_day
Send me an email for every new post (about %{dailyEmailEstimate} per day)
yea i just figured it was a site-specific estimate.
edit: updated my other posts. it’s a setting.
OK, I’ve changed the option to say “Send me an email for every new post, including my own posts”, which I think is easier to understand.
And if it is hard-coded in the software, it isn’t a ‘site specific estimate’.
this setting: max emails per day per user i believe is the one that sets that number. every time i’ve changed it, it changes that estimate.
I’m not really sure what the Max Emails Per Day parameter does, but the hint says:
“Maximum number of emails to send users per day. 0 to disable the limit”
which seems to imply it is a real limit, not an estimate.
Also, the default value is 100 on my system, not 2.
so your default is 100 but the estimate says 2? how does that work? every time i change the setting it changes the estimate on my site. i changed it to 3 the estimate was 3. i changed it to a 200, it says 200. i change it to 50, then the estimate is 50. 
perhaps it also depends on how busy your forum is? i don’t know why it’s different for you. 
As I said above, the 2 was explicitly in the text for that option, so it doesn’t look like an estimate based on traffic. Since moving to Discourse, my forum has averaged about 10 posts a day, but this is the quiet time of the year for a college-oriented sports list, during football season the number goes up significantly.
If I look at messages that were migrated over (the history goes back to 2003, though the list started in 1991), the average has probably been about 15 messages/day.
User documentation is not really Discourse’s strong suit, but I’ve had documentation issues with Mailman and WordPress, too. If Discourse wants to hire me to write documentation, I’m available.
