how can i update?

I think version: Serendipity 1.1-beta5 and PHP 4.4.4

In that section it says:
Mark this entry as a Sticky Post
Hide from article overview / frontpage
Hide content in RSS

Entries can be read by:

Myself Everyone Co-authors

I don't see anything for 'password'

I have installed the plug-in ... how do you make it password protected? I see where you can just make it so the author can see it.

Is there a way for everyone to see the title, but only people with my passoword can read the whole entry?

thanks!

Is there a way to password a particular post so that the title of the post is shown but readers have to have the password to view it?

How do I download and install new plugins into my blog?? thanks!
