Not so far ago I downloaded the archive minibb.zip, changed $mod_rewrite to TRUE and recognized that there is no .htaccess with directions to mod_rewrite. What should I do?

Create this file manually, read our manual etc.

It's not included by default, of course... it's too specific option and not always accessible. If you know what it is should be created for, you should able to know how to create it.

If you know what it is should be created for, you should able to know how to create it.
But cannot you help me in creating? I have one .htaccess but I think it won't work...

Oh, I found .htaccess file in manual :) here's it:
RewriteEngine On
RewriteRule ^index\.html$ ./index.php?mdrw=on
RewriteRule ^manual\.html$ ./index.php?action=manual&mdrw=on
RewriteRule ^([0-9]+)_([0-9]+)_([-0-9]+)\.html$ ./index.php?action=vthread&forum=$1&topic=$2&page=$3&mdrw=on
RewriteRule ^([0-9]+)_([-0-9]+)\.html$ ./index.php?action=vtopic&forum=$1&page=$2&mdrw=on

Manual contains almost everything ;-)

Paul
not everything :) if i'am right, i haven't information about including global moderators

Not sure what do you mean by global moderators, but here it is:

Moderators Definition

Not sure what do you mean by global moderators
yes, maybe i described it not correctly but it's when $isMod sets to 1. Remember?

Remember?
nope I don't.
