i would agree 100% - we have the friends list so surely its not that difficult to add chat into there??
the skype thing works ok with your club members (that u already have added ofc) and regular playing partners - but if i want to be able to message people on my friends list to try organizing a game of skins at RSG, without going through the whole process of setting up the game then inviting everybody (one at a time) from the list only for them all to deny (one at a time also)..... it sucks
an IM feature would be really nice
