@Fleur569 - you don't drag the emoticons, you just click on it underneath the post box (don't know what to call the area that we type in...below that box where you see the line of emoticons. click the ones you like and they fill in where ever your cursor is in the sentence above!
I love these emoticons!
Anyway - feel free to practice in this thread - consider it a payment for the pretty banner you provided!
Cheers
