hi kath
if you click on forums on the left of the white bar on the top of your page you will find the index of all the forums available here on PC. when you see one that interests you you click on that forum. if you have a question you want to post in that forum then you click on new thread just above the blue bar that says threads in forum. a thread is simply the questions members post seeking input from other members. type in your question and hit submit new thread at the bottom. after it has posted you then go up to the top right of the blue bar and click on thread tools and choose subscribe to this thread. to check and see if anybody has commented on your post, you simply check My profile on the left side of the blue bar on top and it will take to the area that has all your subscribed threads that have had responses. hope this helps.
