I just had to run some updates on the database that will require you to update your options. If you had already configured your options this morning then you will need to do them again as this update just overwrote those settings (it looked like only 2 people were effected).
To update your options, go to your User Control Panel (UserCP) and then click on Edit Options in the left hand column. Alternatively you can use this link
to go strait there.
The main options that many of you will want to change is the "Default Thread Subscription Mode" which is currently set to instant notification. If you don't want the notification emails sent, simply set that to one of the other options that suits your needs.
You will also want to set your time zone in the system as well as other communication and notification settings.
Thanks for your patience, once your account is tuned to your liking you should be all set as not other major changes are anticipated in the near future.
