Thanks. I am aware of how to make user accounts. However, I wasn't sure this is what you were instructing me to do. Although mac's fast user switching is fun to watch, I still would not go through the hastle of switching in and out of my account just for limewire. I won't bore you with the customization details of my current account, but they are difficult to setup and time consuming to reproduce. Since I've heard quite a few complaints from other users I am somewhat confident that Limewire will attempt to fix this ram sucking trend.
