Honestly I don't understand in whole what you are trying to discuss.gtrabant
, if you mean an option which allows to subscribe to the WHOLE forums and get notification by email if ANY new message has been posted, then this option is available only to admin and is called $emailadmposts
I doubt that it is needed to provide such option for each user, even if you have small forums. Providing a lot of fake accounts, I could do about 100 fake subscriptions which will kill your server sometimes. Sending an email is a very resource-heavy
I could develop such addon specially for you for about $250. I doubt I will develop it as a paid-addon since I don't recommend anybody to use such option, and, you know... developing miniBB stuff I release ONLY the things which I personally recommend to use ;-)
Also take a look at the option$emptySubscribe=TRUE; Uncomment and set to TRUE if you want your users may subscribe to the topic without posting some text.
Anything else regarding checking of forums is written above by our members. IMHO, Forums Checker
is the tool which is probably the best for your needs. Think different.
