can't login to wiki

[TK Soh]

I had wiki sent me the login password twice, but kept getting "Sorry,
wrong password." when I tried to login.

There's also a note on the UserPreference page:

=====
Logging in

If want to re-login, just use Name and Password and click on Login. If
you forgot your password, provide your email address and click on Mail
me my account data.
=====

But I can't find the "Login" button.

The password wiki sent to me looked like this:

   Login Password: {SHA}xxxxxxxxxxxxxxxxx

I tried to paste in the password field both with and without "{SHA}",
but still couldn't get it to work. What am I missing?
