Newbie threads are fine it's a good way to introduce yourself.
If you are having difficulty keeping track of threads you have posted on, you can go into your profile, on the top right hand corner you will find a button labelled, 'Profile Options.' Press on that and a drop down menu will appear with the option of selecting your last posts. You can then find the thread you posted in by clicking either on the post number or the topic title.

Welcome aboard.
