I am finding the only way I can add the emoticons is to post then edit - hence all my editing. You edit away Aileen!!!
Westie (hope you don't mind me calling you that!), you don't need to post and then edit those posts in order to add emoticons.
I think I know what you've been doing though. It looks like you've been using the Quick Reply box at the bottom of each page to type in your comments, then posting them and clicking on 'Edit', which takes you to the big Main Reply box where all the emoticons, and other functions, are. You should just start typing in the Quick Reply box then, if you want to add emoticons, click on the little 'Advanced' box which will take you to the Main Reply one. You can then add the emotions, carry on typing, and preview your post to see what it looks like before sending it. Also you can do as many edits as you like before posting and nobody will be any the wiser.
Hope that makes sense, if not ask Mark.
