here at uni we have a load of people who have itunes and make full use of its music sharing capabilities over the network but i have a few questions: 1. sometimes when trying to access a library i get the message "sorry this user only accepts 5 users a day" is this a feature of 4.7.1? i cant see any options to set limits. i never used to get it.. 2. are there issues with sharing and different versions of itunes? some people are refusing to upgrade to the newest version of itunes because they claim that they can't share. however, i reckon that this is because the new version can only share with the new version. am i right?
