Vinum & Firewire?

[Drew Tomlinson]

I was wondering if you've had any time to look at this?  If I am a nusiance,
please tell me and I'll go away.  If you're still extremely busy, I'll
continue to wait patiently.

Thanks,

Drew

I’m sorry that the format was mangled.  I am forced to use 
Microsoft Outlook at work which is where I write most of my email.

Hopefully you will find this version much more readable.  I
appreciate any assistance you may give when you have time.

Thanks,
