It is very easy to find and view new postings if you go to "Active Topics" on the top menu of the forum. You can select any time frame you wish. As default, Active Topics will tell you what is new since your last visit. Try it and see.
In Active Topics, the entire list can be "marked as read" with the little two-tone folder icon in the upper left corner. This resets your last visit to the current date and time.
In addition, forums and topics with new postings since your last visit will be marked with a purple/pink folder on the left side in the forum and topic listings.
You can find other tips on viewing and posting in "Navigating the AYP Forums" here in the Overview and Announcements Forum.
For several reasons, the subscription feature (email notification of new postings) has not been activated for the AYP Forums at this time, so it is necessary to check "Active Topics" here on the website to see what is new.
Wishing you the best on your chosen path. Practice wisely, and enjoy!
