On one of the MANY different phases my board has gone though, i had this code put in the users profile
Response.Write" <tr>" & vbNewLine & _
" <td class=category2 align=""center"" colspan=""2"">You may delete all cookies set by these forums by selecting the ""logout"" button at the top of any page.</font>" & vbNewLine
Response.Write" <font face=""" & strDefaultFontFace & """ size=""" & strDefaultFontSize & """ color=""" & strForumFontColor & """>Or alternatively by clicking this link: <a href=""javascript:openWindow('pop_delete_cookie.asp?')""" & dWStatus("Delete Cookies set by this Forum") & " tabindex=""-1""><acronym title=""Delete Cookies set by this Forum""><b>Delete Forum Cookies</b></acronym></a></font></td>" & vbNewline & _
" </tr>" & vbNewLine " </tr>" & vbNewLine
And the code for the page pop_delete_cookie.asp is
<%@ Language=VBScript %>
<%option Explicit
Response.Buffer=True
Dim objCookie
Response.Write "<p><font face=""arial"" size=""3"">Deleting cookies...</font><BR><BR>"
For Each objCookie In Request.Cookies
Response.Cookies(objCookie).Expires = "September 1, 1999"
Next
Response.Write "<p><font face=""arial"" size=""3"">Done.</font>" & vbNewLine & _
" <script language=""javascript1.2"">self.opener.location.reload();</script>" & vbNewLine
Response.Write "<body onLoad=""setTimeout(window.close, 2000)"">" & vbNewLine
%>
It worked for me when i had it on my board, i just don't have it there anymore for one reason or another.
I forget who originally whote the code.
Hope this helps
