Stop a member from contributing in a particular discussion

Is it possible to exclude an

Individual member from Participating in a particular discussion.

Thanks in advance.

Not that i know of sorry

Not to 1 conversation no, you can make that user a group of own and prevent from posting in the section. That is about it besides simply deleting his posts.

you can try this

create a new javascript set it to in topics

Code:


$(function(){
var notallow = ['1','97664']; // list of user id's
var nopassurl = "member-from-contributing"; // url to block
var redirurl = "/"; // redirect url
var redorremv = "remove"; // remove or redirect
var alrmsg = "You Can Not View This";  // alert message on redirect
var gusrid = _userdata.user_id;
var cururl = location.href;
for(var i = 0; i< notallow.length; i++){
if (redorremv == "redirect"){   
if    (cururl.match(nopassurl)){}else{return;};
   if (gusrid == notallow[i]){
      alert(alrmsg);
      location.href = redirurl;   
   }}
   if (redorremv == "remove"){   
      if    (cururl.match(nopassurl)){}else{return;};
   if (gusrid == notallow[i]){
            $('a[href*="&mode=reply"]').attr('style','display:none');
            $('#quick_reply').attr('style','display:none');
   }}}
});


notallow = ['1','97664']; < list of user id's you want to prevent
var nopassurl = "member-from-contributing"; << url you want to to block
var redirurl = "/"; < url you want to redirect the prevented member to
var redorremv = "remove"; << two choices remove and redirect .. remove removes the reply & quick reply options and redirect takes them to another page
var alrmsg = "You Can Not View This"; << message that will be displayed on page redirect

Thanks for the replies. Deleting his posts seems to be working. 
Problem solved.
