Forgiveness is easy, and everyone has been new to this at one time or another.
To start a new thread, you should be in the forum you want. Oddly enough, you are in the right forum for posting questions… Go to the bottom of your screen, where there will be a “forum jump/search forums” Once you are in that thread, you click on the Red link at the top of the page that says Threads in Forum: To the right is the FORUM TOOLS. Click on that, and you will have post a new thread
At each posting on the bottom right there is a quote link, and your reply will have everything the poster had written
That is in you public profile. You have to be signed in before you can add anything.
Let me know if there is anything else!
