I used to use Invision Board and you could "subscribe" to a thread and receive emails of new posts without having to actually post. This is very useful! Is there any way to do this? Even on this board when I see a mod discussion I would like to follow as it developes it would be nice to just click a button rather than having to post some dumb reply that just takes up room on the board. ;)
Click on the "notify" button :)
Notify will email a notification, but in vBulletin you have the option to view all subscribed threads to see if there is any activity.
That's what I would like to see in SMF or in a Mod.
