Ok, I tried it with changing action="nothing.asp" to action="" in the Email Subscription MOD in Forum.asp
<%'#################### Email Subscription MOD, start added code ###################%>
<form method=post action="" name="dummyForm">
<%'################################ End added code #################################%>
and everything seems to work fine.
Anders, if you find this to be ok in changing it to action="" then you may want to update your MOD or keep it in mind for ver5
