But there is a way around it.
When you post, at the end there are four boxes under Options - one of these is Disable Smilies In This Post, so click on that and problem solved! If you do post and get this problem, use the Edit button at the bottom right of your post, and click on the Disable Smilies.
I've been back and edited your post, so that your original link works perfectly.
Hope you don't mind me posting this publicly - hopefully it may help someone else in the future who has the same problem.
