I was logged into the administrative section of Trawler Forum at the same time as another forum which we are working on. I was running some maintenance scripts to set default settings and accidentally wiped away and set the defaults here. It looks like it effected about 66 accounts but I don't know which ones so if you had updated any of the following settings you will need to reset them (SORRY!)
Default thread subscription - This is the one that will send you an email as soon as someone replies to a post you had made.
Receive Email from Administrators - This will opt you out of getting any emails from us like newsletters or happy holiday stuff.
Receive Private Messages - This allows you to turn off the private message feature.
You can update these settings in the UserCP >> Edit Options page. Here is a link directly to that page:
I am very sorry about this inconvenience!
