It requires python 2.2 or higher

"/forum/memberlist.php?order=mid(passwd," + str(i + 1) + ",1),uid&prevorder=uid&direction=ASC&page=" + str(page))

you can order the memberlist by password or more specificly one character of the password. and thus determine its contents

We'll just see about that

>Plugin that a 3rd party made has some issues that need to be cleared up.

yes and this site is running it, it could easily be defaced

I think you had better look at your code again. The forum memberlist.php does not allow you to sort the user list. Quit spreading this fud until you know what you are talking about. Here is the code that retrieves the member list.

$memberlistsql = DB_query("SELECT * FROM {$_TABLES['users']} WHERE uid <> 1 ORDER BY regdate");

The order by is not changeable!

I also ran your python script and could not get it to run -- by the way my python version is 2.3.

Sorry Tom, you can order it.
http://www.geeklog.net/forum/memberlist.php?order=username&prevorder=uid&direction=DESC&page=1

The headings are links.

I can get the script to run a while but then it pukes.

tomw, sorry but there are huge security issues with the forum plugin(I was the one defending geeklog earlier in this thread). I suggest anybody using it take it down until it is fixed.

I was the one replying to the other things but anyway I looked at the python script. I got it to ran. It puked 5 minutes in but his theory is right.

I guess it won't hurt for me to explain it here since anybody can look at his script.

You CAN order by anything on the memberlist page... I can't say that I have looked at the code for the forum plugin at all. Hell I haven't even installed it on my own personal site. But if they're using the latest version of the forum on geeklog.net you can sort by whatever you want. Order it anyway you want and more.

EXAMPLE.
http://www.geeklog.net/forum/memberlist.php?order=uid&direction=ASC

His python script didn't work for me but I could write something in another language that did the exact same thing. His theory is correct.

Heres how it works.

memberlist.php?order=mid(passwd," + str(i + 1) ",1),uid&prevorder=uid&direction=ASC&page=" + str(page)).read()

What he is doing is pulling back a character at a time and ordering the page based on the one character that is returned from the password field. From this he can compare it to where your own placement is on the return and tell if its higher or lower or equal. If you did look at the python script it is constantly changing your own password so it can compare it better.

I believe this is how it was working if not, that way should work :-p

I admit I wasn't looking at the new version since it hasn't been released officially yet. The version for download here and most widely used does not have a sortable memberlist.
