hey, does anybody remember an addin (i think it was) which opens up an alert box when another user tries to start a conversation with you, and it also tells you if they close it aswell?
if you can get any information back to me, it would be much appreciated ;D
thx1

This list will give you all the addins/plugins available for that:

Personally I prefer OpenConvo as it has the most features for this function (it is also the one that popups with a toast, which you want).

thx
