RE: adjusting control surface throws
Any member in good standing can post photo's.
Once you place an original post in a thread, or reply/comment to a post and save it to the thread, you can go in and edit the post. You will see a link at the bottom of the edit screen to add items - pictures.
Try it. Edit your post and look at the bottom. You will see "Upload More Files?" Click on the link and add a photo or two or three.. don't forget to click ok OK when done each screen.
