in reply to Re: Another commenting question,
in thread Another commenting question,

$x++; # keep track of how many users have logged in
Actually, I think that's a poor comment, unless the text around it makes it make more sense. I'd prefer to see something like:
$x++; # $x is number of users currently logged in, and we have a new o +ne
Hmm. On re-reading your comment, I can't tell whether you meant total number of users that have ever logged in, or whether it's a current count. That's probably why I already flagged it as bad. {grin}

Even better would be to never use $x for something like that:

$current_users++; # we have a new one
That's a lot better.

Better variable name

    Is perhaps better (to make it obvious that it is a counter when it is not associated with the ++ operator).
