[albatross-users] New tag reference

[Michael C. Neel]

Dave,

	You're all over the docs this week =)  Yes, this looks really
awesome and helps show the "full circle" of a form.  Since using
albatross I now know the request objects are from the cgi FieldStorage
class, or at least act like they are; but when I started out I'd never
programmed with the cgi module (nor do I intend to, lol) so I was a bit
lost.  Those that have used the cgi module probably don't need this, but
those of us that didn't will find this vey helpful.

	At some point you might consider documenting these objects
completely (read: cut-n-paste from the cgi.Fieldstorage docs) just to
have it all in one place; but this isn't all that important.

Mike
