Unregistered's Numbering System

PROBLEM:
I have a forum that unregistered users can post in. Although some choose to change their "guest" name to something other than "Unregistered", most don't, and on busy threads, confusion occurs.

SOLUTION:
In the newreply and newthread files, instead of assigning "Unregistered" to the username of posters who aren't signed in, use "Unregistered" plus a 4 digit random number. This new username doesn't need to be cookied to a user, its just to keep each post unique for reference.

I'm working on this myself, and I think its just required in newreply and newthread, but if someone already has something like this, please post it here.

Nice idea, and very simple to execute.

In sessions.php, under your admin folder, find

PHP Code:

$bbuserinfo['username']=iif ($loginusername=="","Unregistered",htmlspecialchars($loginusername)); 


Now. You have basically two options. One is to remove the Unregistered at all, so people will HAVE to enter a new username. If you want this, replace the above line with

PHP Code:

$bbuserinfo['username']=iif ($loginusername=="","",htmlspecialchars($loginusername)); 


and that's it.

If you still want to do the random number thing, you will need to replace

PHP Code:

if ($session['userid']==0) {
  $bbuserinfo = $session;
  $bbuserinfo['userid'] = 0;
  $bbuserinfo['username']=iif ($loginusername=="","Unregistered",htmlspecialchars($loginusername)); 


with

PHP Code:

if ($session['userid']==0) {
  $unreg = Unregistered;
  $unreg .= rand (1000,9999);
  $bbuserinfo = $session;
  $bbuserinfo['userid'] = 0;
  $bbuserinfo['username']=iif ($loginusername=="","$unreg",htmlspecialchars($loginusername)); 


Thanks, that will be useful, I think instead of random numbers, I'm going to give them a random pleasant name, the code kind of looks like the attached.

EDIT: Actually, I think I'm going to use the Captain Underpants names, which should give me over 17,000 possibilities. See attached for sample code.
