Hey guys. This is a random snippet I made to keep track of:

• How many times a user has joined the channel (increases by 1 every time someone joins the channel.)
• How many users have joined the channel (increases by 1 every time a user joins the channel who hasn't joined before.)

Before you use, type this:
/set %chan <#channel>
This will set the channel you're keeping progress of. ex:
/set %chan #mIRC

Cheers!

on *:join:%chan: {
  inc %f
  if ($nick !isin %g) {
    set %g %g $nick
  }
  notice $nick Welcome to %chan $+ , $nick $+ !
  notice $nick Amount of joins: %f
  tokenize 32 %g
  notice $nick Amount of people joined: $numtok(%g,32)
}
