I'm not sure how much time I've wasted getting multiplayer games setup in the last 3 months, but it's a lot. It used to work just fine, having all the time you wanted to send out invites, and replace people that decline them. But now you either need to have everyone under the sun on your friendslist, or fast typing skills to get it to work. (I can type fast but other people take numerous tries to get a 4some going) Add to that if you 2 of the 3 people accept, and 1 doesnt, and you wish to replace them, you have to go thru the entire process again.
I'm sure I'm beating a dead horse here, but c'mon WGT, this is a very very simple fix I imagine, yet something that frustrates nearly all your multiplayer players on a daily basis.
