here is one trick by that you can just private users with your un-registered id by using 3.02 lite or beta or 3.05, simple be in chatroom with other id and disconect your internet (dnt exit the mig application) then register new id with same application of mig and enter any number bla bla,
Then login the new id which is not activated by authentication code
then you will see that the room window is still there and you can private any user manualy by going to "enter username" option in room just using 3.02 beta, lite or 3.05
(in the whole process dnt exit your mig application)
i have not try this trick from about month ago may be the bug is fixed but you can give one try, as it is an old trick
dont use this trick for abusing or teasing some one
