Simon has added a new feature to the forums that allows you to add your save right into your post. Simply put the URL of the save (pow dertoy.co.uk/View.html?ID=2198) into your post and it will auto-embed. No need for save tags anymore!
No, I don't think you read the question properly, and as a note in future, at least make a new thread saying this doesn't work, as posting on old threads that haven't been posted on over a few days is often frowned upon.
Even better, you could use the searchbar in the top right hand corner and type in "Posting Saves" or something, finding a couple of threads and see if you can find anything on the subject. If not, do what the paragraph above tells you to do.
