Hi Kate,
I am sorry that this issue has impacted on your learning experience. There was a change made to Forum settings yesterday but it should not have had this impact on your posts.
Can you please let me know which course(s) the phenomena occurred in and I will look into it for you?
If it has happened to anyone else I would be grateful if you recorded it here along with course(s) affected.
In the meantime, if you were up to date with reading forum posts, you can mark them as unread in bulk - either by clicking on the tick next to Unread to clear the whole forum or by clicking on the tick next to the number of unread posts to clear that thread only:
