Hello, welcome to this little phpBB Benchmarking script :)<p>

At the moment there are:<br>
<table>

<tr><td align="right"><?=$nr_of_topics?></td><td>Topics</td></tr>
<tr><td align="right"><?=$nr_of_forums?></td><td>Forums</td></tr>
<tr><td align="right"><?=$nr_of_posts?></td><td>Posts</td></tr>
</table>
<p>
What do you want to create?<p>

<form method="get" action="<?=$PHP_SELF?>">
<input type="text" name="users" size="3"> Users<br>
<input type="text" name="forums" size="3"> Forums/categories<br>

it will run from on the server. ie /www/yourdomain.com/phpBB)

Step 2: Edit config.php and change the following values:

The url fields my work for you if you're running phpBB from a domain 
like this: http://www.phpbb.com/phpBB

However if you access phpBB like this: http://www.domain.com/~you/phpBB you
will have to change these values.

Also, config.php MUST be writeable by the webserver or the install will fail.
To set this on UNIX systems you can use chmod
ie: chmod 777 config.php (after the install if finsished set it back to 755 
via chmod 755 config.php so it can't be written by anyone again.)";
