thanks for your reply,
linked notes about readable mambo code are pleasant

in fact now i'm somewhere between mamboserver.com and phprs.cz
(f.e. because they have my language version)
combined with phpbb.com or phorum.org

seems i will need to administrate two products together
(for page client) maybe with different "look and feel"
(for admin maybe with two separate user databases)

probably i will try for every new artile create new forum thread with one entry containing link to article and assigned to article's author (hope one day with "automated solution")
