Does "echo save-passwords" **force** the saving (without letting the
user not save them?) Or does the Windows GUI give the user a choice?
(Or does it always only give the users a choice if "echo
save-passwords" was received?.) Does it save usernames, passwords, and
passphrases (for keys), or just passwords?

OK, but It isn't clear to me what the OpenVPN client software does
when it gets "forget-password": does it erase the password(s) **it**
has saved in memory and then pass "forget-passwords" through the
management interface? Or just pass it on without doing anything?

Thanks. I will probably do the same for Tunnelblick. (Sometime : )

Would "echo disable-save-passwords" (two hyphens, right?) make it so
the user **can't** save passwords through the Windows GUI, and
otherwise they would be able to? (I am not familiar enough with the
Windows GUI to know if it usually offers that to the user; Tunnelblick
offers separate checkboxes to save the username and password unless
they are explicitly disabled via the configuration's Tunnelblick
options.)

Absolutely! +1
