Create TPL files hidden/tpl/pages/users/users_title_en.tpl and hidden/tpl/pages/users/users_default_en.tpl. For title put "Users", leave users_default_en.tpl empty for now.
Now we have to generate grid's HTML. Go to hidden/inc/grids/users/users_grid.class.php and uncomment the row with $this->generate_html();. Point your browser to http://tft.myhost/users.php and you should see the generated HTML. Select, copy and paste it in hidden/tpl/pages/users/users_default_en.tpl. Go back to hidden/inc/grids/users/users_grid.class.php and comment row $this->generate_html();.
Now we have to create TPL files for the grid. Create hidden/tpl/grids/users_grid.tpl with content:
{include file="grids/`$_language`/users_grid_`$_language`.tpl"}
Create file hidden/tpl/grids/en/users_grid_en.tpl. Go to hidden/tpl/pages/users/users_default_en.tpl and find <!-- *** CUT top -->. Select to (inclusive) <!-- *** CUT bottom -->, cut and paste in hidden/tpl/grids/en/users_grid_en.tpl.
In the place of cutted content in hidden/tpl/pages/users/users_default_en.tpl put {include file="grids/users_grid.tpl"} so it look like:
...
<div id="users_grid_div">
{include file="grids/users_grid.tpl"}
</div>
...
