Sometimes,peoples ignorance and stupidity really astounds me.The Clean Limewire project was started by TruStarwarrior who is now being helped by VTOLfreak,the idea of a CLEAN Limewire is exactly that,it is clean,no spyware,tojans blah blah blah.
Both TruStarwarrior and VTOLfreak have been avid fans of Limewire, before and after the 'Clean' project was born have encouraged users to upgrade to the Pro version of Limewire.
Clean Limewire,is basically to let the users know what Limewire is all about without the bundled crap that goes with the free version.
As for the reminder about upgrading to Pro every time you start up Clean Limewire...deal with it, or upgrade to the Pro,which is the whole point.
