[ExtractStream] Re: RELEASED: TyTool Alpha #4. UK Support.

[Nicholas D. Davies]

Josh,
Staying true to my word, I have sent you $30 via paypal for
Releasing the UK version of TyTool. To encourage further 
Development I will continue to send you more money as we see 
new releases with new features that I've requested, ie 
status line changes, integrated MPG muxing/cut/split tools etc.

I applaud your dedication to this kick-ass utility and 
Encourage others to financially support you to purchase the
Hardware you needs in order to continue supporting us, or just
To give you a well earned great night out to blow it on a
Nice cold beer!!!!

Keep up the good work. I look forward to the next release.

Nokia
