Hello and Welcome to the new My Oracle Support Community for PeopleTools!
All of the My Oracle Support Communities have been moved to a new platform, which provides better search capabilities and added functionality.
Check out the Getting Started Community for complete information and an FAQ.
There's also a series of webcasts to convey the new features in the Community spaces. See Note 1615047.1 for the schedule and register.
To find the list of discussion threads, click on the Content tab from the main PeopleTools - PSFT (MOSC) start page. From the Content tab, you can filter by text, open/closed questions, and discussion threads.
