user level hack?

hi everyone…
i was looking to see if anyone has hacked the user levels to change access to one specific area. here’s my debacle…
i hacked the ‘template’ page to list among the common files a text file that is pulled into a template to generate dyanamic info (in this case, the details on a monthly meeting). while i don’t think i want my users jumping to page that loads the index.php file, i would like our post-capable users (four or so) to be able to edit that meeting info file.
i’m thinking about a template2.php… with maybe just the text file being displayed? and adding a link from the post page to that template2.php?
i’m going to work on this some more, but has anyone done something like this? any other ideas?
thanks, everyone,
