Not a complicated MOD, but helpful I think. It adds a link to down.asp in the Admin options. A bit more straightforward than the default way of logging into Admin Options and then going back to default.asp in clicking the lock icon, or typing in down.asp into the browser address box.
In admin_home.asp find line #153 with the following:
" <LI><span class=""spnMessageText""><a href=""setup.asp"">Check Installation</a></span><font size=""" & strFooterFontSize & """><b> (Run after each upgrade !)</b></font></LI>" & vbNewLine & _
and add this to the line after it (#154)
" <LI><span class=""spnMessageText""><a href=""down.asp"">Close Forum for Maintenance</a></span></LI>" & vbNewLine & _
