Two ways I can help here:

1. Top green bar click on Quick Links then click today's post - that will give you everything that has been posted on today's date. Or what Fooze said. Use that in a particular group you are viewing to get the newest threads.

2. Click my profile. Then on the side bar under settings and options, click on edit options. There you can read through and select various options such as automatically subscribe to a thread that you post in. That's what I did made it a lot easier to follow most threads I'm interested in.

Hope this helps.
