Now dependent on class.inputfilter_clean.php found in
package http://www.phpclasses.org/browse/file/8942.html

cp bbs_xyz.tgz   /srv/www/htdocs (for instance)
    cd '/srv/www/htdocs/'
    tar -xvzf bbs_xyz.tgz
    chmod 777 sys_config.inc
    mkdir /srv/www/htdocs/bbs
    mkdir /srv/www/htdocs/bbs/2006 (default forum, for instance)
    chmod -R 777 /srv/www/htdocs/bbs 

now point your browser at bbsconfig.inc 

Note: robot forum spammers are currently kept
somewhat under control with a hard-coded list
of keywords and domain names in isPorno.inc.

This does require ongoing editing of isPorno.inc
It wouldn't take much to add a captcha function
to the new_post function. I may do tha someday.
I haven't done it yet, because the users 
might not like the extra step. 

My users really do like this forum.
