There are some options to try and help with this. You can set the default
action for the various categories (defaulting to "discard" for spam, for
example), and you can have different actions for ham below a threshold and
spam above a threshold ("train as spam" for all spam below 0.7 and "discard"
for all spam above 0.7, for example). You can set the number of messages of
each type (ham, spam, unsure) to display per page (this defaults to
something like 100,000, so in all likelihood all messages for that day).

For example, here you could set the rows per category to something like 50,
and not see most of the spam (without clicking to the next page).

The SMTP proxy is one way around this. It's an alternative training method
where you forward messages ("as an attachment" with Netscape) to a special
address (e.g. spambayes-spam at localhost or spambayes-ham at localhost) and do
the training that way. It's (currently) one message at a time, though, so
perhaps not a convenient solution.
A better alternative, but one that's not quite ready yet, would be the
pop3dnd script (it's in the source archive, but really needs a bit more work
and a lot more testing before it's ready for prime time and a binary
release). This lets you do drag-and-drop training in your regular mailer
(without actually integrating into the mailer, so it's still unimportant
which one you use). Not much use now, but some day...

I've added a feature request tracker for this, so will get to it at some
point (unless someone beats me to it).

Yes, that's correct.

There is, with some catches. To do this you turn on the advanced option to
add the "score" header to messages (in the "Headers" section on the Advanced
Configuration page), and the advanced option to show the "score" column in
the review page (in the "Interface Options" section on the Advanced
The main catch is that there's a bug in all the current releases which means
that the scores are sorted as strings, which means it goes something like
"1, 10, 11, 12, ..., 2, 20, ...". I fixed this a few days ago, but the
change won't make it out into a released version for a while. Apart from
that, it should mostly work.

I'll try and remember to add this to the appropriate documentation. It
seems like a sensible addition - thanks!

We try - note that there are periods when all the regular people doing the
answering get quite busy at the same time, and so replies are slow to come.
They do come eventually, though. (And this is not one of those times). The
difference in time zones (e.g. I'm in NZ; I think Adam is in the US) can
also mean that responses are delayed sometimes.
Please always include the list (spambayes at python.org) in your replies
(reply-all), and please don't send me personal mail about SpamBayes. This
way, you get everyone's help, and avoid a lack of replies when I'm busy.
