Can anyone explain, or point out an appropriate page which will tell
me, what the difference is between these actions when I'm in
Newsgroups view? This is in version 12.0.1606, and Help is totally
silent (or else I don't know where to look).

View > Refresh (= F5) (Also on toolbar)
Tools > Synchronize all (Also on toolbar)
Tools > Synchronize newsgroup
Tools > Get next n headers (On toolbar: Headers)
Tools > Get New headers
Synchronize account (Only on toolbar)

Sometimes, when I select a newsgroup in the folder pane, the status
bar tells me that WLMail is connecting to the server and checking
for messages. Sometimes it doesn't, and it seems to depend on where
I clicked previously.

What constitutes a New header? Or a New message? Is there a time
span involved?

And the same questions really apply to Synchronization settings, of
which there seem to be a bewildering variety, in several places.

Lastly, what does 'Catch up' mean, and what's the difference between
'Purge' and 'Delete'?

I'm sure I'm not the only one who needs a bit of guidance. Happy New
Year everybody!
