Quote from koufu »Hi guys,
Here's a new python script that allows your SMP server to have OPs, use the !kick command, and the !# command (to allow a player to give themselves items!)
You can add OPs to your server by adding their names to the oplist.txt file. As well, you can add a list of blocks that non-ops can give themselves into the blocklist.txt file.
Further instructions are located in README.txt
This is the latest release and fixes a major security hole, in addition to a few small bugfixes and MAXPLAYERS YAY:
