Wow,
great work, and very generous of you too.

Would it be possible for you to do one to accompany the
Windows 98 SE Unofficial Service Pack?
The service pack is at version 2.1a. If you'll do it, could you leave out the version number, so that it's good for future versions? So that it reads just like your Windows 2000 Unofficial Service Pack 5, except without the version number, thus:
Microsoft®Windows 98 Second Edition™Unofficial Service Pack
OR
Microsoft®Windows 98 SE™Unofficial Service Pack
(the first one is strictly correct, but the second one would be fine if it is easier for you!)
If you do it, I'll let Gape and Petr (the guys behind the Unofficial SP) and everyone on the forums know about your fine work.
Thanks for the offer, and Happy New Year.
