Welcome from an Iowa Girl!
When first on the board, I found that when in doubt, I could always go "Home". That's where all the topics are listed. Once you have posted on a thread it will come up in your "Subscribed Threads" and you can see other replies. Now to find this, go to the "Quick Links" tab and a drop down will be found with "Subscribed Threads" first up. Click on that and you will find the threads you have replied to. Good luck, it takes a bit, but like everything else, the more you use it the more it becomes familiar!
