I have 4 pcs available to me and possible 2 more desktops + 2 laptops. My first pc has WinXP Pro SP1 on a 15/2 fiber connection. It's been highly tweaked with different services and shell modifications. This is a AMD 2100+ 1.73 ghz 512mb ram system. My second pc has WinXP Home SP2 on a 10/2 cable connection. It's probably my most 'normal' pc. This is also an AMD 2100+ 1.73 ghz 512 ram. My third pc has WinXP Pro (no service packs) on a 10/2 cable connection. It's startup items are also highly tweaked. This, however, is quite an old system. It's a Pentium 400 Mhz with 128mb ram. Very useful for testing the webui on slower systems. My fourth pc has Windows 2000 Pro (SP1) on a different 10/2 cable connection. Default services and startup items. Another old pc, an AMD 400 Mhz, 128mb ram. I can test any browser you'd like, I have Internet Explorer 6 on all the pcs (might be 5 on the win2000 box) as well as Firefox 1.5.0.2 on the two amd 2100+'s. I've also got IE2 and Opera on my first pc. I've only betatested about 20-30 things but I'd probably be able to help you well with the µTorrent webui. I'd say I know a decent amount about µTorrent and use almost every feature of it to some extent. I'm also nuts about tweaking everything to the last gram so I usually find some bugs here and there.
