If you go to the navigation menu, tap people, tap yourself, tap posts, then tap the down arrow and tap on topics, you can see all threads you've started. But, not everything is 100% functional right now, they're still in the process of working out all the kinks and getting everything switched over. Just be patient.

It's easy to say the old version was better, because everyone got used to that one. The new one is different, but once you get used to it, I'm sure you'll agree that it's much better.
"What, exactly, is the internet? Basically it is a global network exchanging digitized data in such a way that any computer, anywhere, that is equipped with a device called a 'modem', can make a noise like a duck choking on a kazoo." - Dave Barry
