On alert preferences, all I see is: Messages in Threads Receive an alert when someone... Replies to a watched thread Someone replies to a thread you are watching Attaches a file to a watched thread Someone replies and attaches a file to a thread you are watching Quotes your message Someone directly quotes one of your messages in a thread Likes your message Someone likes one of your messages in a thread Normally, if you just like a post on a thread, and not posted their, you will not be notified if there are new post on that thread. I would like to have another option. If the user likes a post on a the thread he/she will be automatically be "Watching that Thread" and will receive an alert if their are new post on that thread. I would like to set this as default also for all the users. Thanks !
