Are you referring the post owner?

What i mean is if someone publish a new discussion post on the site, this user should automatically subscribe his own discussion?

Yes. Currently when someone creates a discussion they have to remember to select to subscribe to it. But if someone replies that can be set to auto subscribe them.

Linked in with all this though, it seems that even though we have notification emails set up none of those are working, nor is anything being posted to EasySocial despite us having that set, so I suspect something is very wrong somewhere!

Probably best to close this discussion and use the other one I started at https://stackideas.com/forums/discussions-not-apperaing-in-es-news-feed-stream

Thanks!

Are you referring create new discussion form or reply form?

Because the subscribe checkbox only show in reply form.

if you would like those user who reply on the thread then auto subscribe it, you have to enabled this setting from backend -> http://take.ms/SB1jT

Perhaps you can share with us which discussion when someone reply it, system doesn't send email/system notification to that user so we can better have a check?

Thanks - yes we found and enabled the option such that when a user replies they are auto-subscribed, but our issue is that when someone starts a new discussion they are not automatically subscribed to it, which seems sensible they would want to be subscribed to a discussion they created?

At the moment, on our system it seems quite random when emails are sent and when not unfortunately, so I think we need to do a bit more investigating first to see if we can narrow down the issue.

By right whoever reply on the discussion, the post owner should always receive an email notification regardless of whether post owner subscribe on their own discussion or not.

By the way, I've checked your site backend Easydiscuss mail activities page, it seems like all the email still under pending state, may i know do you have setup cronjob on your server yet?

It needed to setup cronjob on your server in order to send out those pending email to your site subscriber, you can refer on our documentation here how to setup it.

https://stackideas.com/docs/easydiscuss/administrators/cronjobs

If you need assistance on this, perhaps you can provide us with your Cpanel access which can setup cronjob on your server, so I will help you setup all of your existing extension like Easyblog/Easydiscuss/Easysocial/Komento.

Thanks, yes it seems we only had EasyDicuss set up for CRON so I have now added in ED and EB

You're welcome, keep us update if you need any assistance for this in the future.
