Cheers for that, didn't realise there was a PC client. But in a way my ignorance to that kind of goes along with my point. I mean, I know ****-loads of people who have Skype, but literally no PC users who'll have Go!Messenger. If it did become popular, then that'd be great, but until then I can either try and convince the people I know to install yet another strange unwelcome program on their PC, so I (and me only) will be able to talk to them using my PSP, or I can simply sign on to MSN or pick up the phone. I dunno, it just doesn't have as much use for me personally as Skype would...
