## MOD Title: Redirect anonymous users to login
## MOD Author: StefanKausL < stefan@kuhlins.de > (Stefan Kuhlins) http://kuhlins.de/
## MOD Description: This very simple MOD redirects anonymous
## users to the login page instead of showing member, groups,
## or profile pages. That way anonymous users can't see
## registered user's data.
## MOD Version: 1.0.8
##
## Installation Level:	Easy
## Installation Time:	1 Minute
## Files To Edit: groupcp.php, memberlist.php, profile.php, viewonline.php
##
## Included Files: n/a

## Author Notes:
##
## To make this MOD work, the forums must be set to registered users only.
## Go to the "Forum Permissions Control" section and
## set "View", "Read", "Post", etc. to "REG".
## This stops guests from viewing, reading, and posting.
##
## Search engines did not see posts that are for registered users only,
## but you can set some forums open to all users including search engines.
## Go to "Forum Permissions Control" in the admin section and
## set "View" and "Read" to "ALL".
##
## Intentionally I didn't put the redirect on my index and search page,
## because I want some visible forums and topics,
## especially for the rules everybody should read before registering.
## But the code will work in the files index.php and search.php as well.
## Just insert the redirect code the same way as for memberlist.php and
## viewonline.php.
##
## CAUTION:
## Do not put the redirect code after init_userprefs($userdata); in
## profile.php, because that way nobody can register!
