I’m guessing you’re using the MyCE forum style, and using that style, here’s how to find your other posts/threads:
If you go into your user profile (click on your name in the yellow box, near the top right of the forum window), and find the “Comments by buel” part, you can then click on any of the comments/posts you’ve made.
This is the one I think you’re looking for: Can’t record vhs tape, get message similar to ‘copy protected’-Please help?
Another way, is to look at any of your posts, such as the one above mine here, you’ll see a little row of icons to the right of your username. Click the icon that looks like a couple of speech bubbles, and you’ll bring up a list of your recent posts.
