<p class="pageac_notes">The characters <b>&nbsp;&nbsp;|\{}[]()#:^$.?+*&nbsp;&nbsp;</b> are treated as special characters in regular expressions and to make them usual characters it is necessary to preceded them with a backslash <b>&nbsp;\&nbsp;</b>. That is why if you haven't checked "Advanced Expression" option the script is adding backslashes for you.</p>
<p class="pageac_notes">For example if you're setting access to <b>photos module</b> then you should write rule as<br /><b>m/photos/</b></p>
<p class="pageac_notes">Those experienced members who knows what are UNIX-style regular epxressions and how to use it may tick the "Advanced Expression" checkbox during access rule creation and use the full power of regular expressions.</p>
