How can you make yahoo contacts see custom msn emoticons?

When I'm chatting with other msn contacts we can see each other's custom emoticons with no problems; on the other hand when I'm chatting with yahoo contacts (via my msn address) I can't even send custom emoticons -- is there any way of enabling me to send custom emoticons in conversations with yahoo contacts?|||Simple answer is no unfortunately. MSN is the only program that lets you send custom emotes :( So your contacts will need to install it to see them.
