[Pmwiki-users] PMwiki for different projects

[Michael Hessler]

I just installed pmwiki, but I'm not yet experienced using wikis.

I would like to use pmwiki for different applications and topics, which 
are attainable from an existing Website with different, partly 
password-protected HTML-pages.

Important: The users of one topic should not see the content of an other 
topic.

How should I solve this problem (without installing pmwiki several
times)?

Thank You.
Michael
