For now, you'll only find some scripts here:
DisplayMsgByMID.hsc: Enter a Message-ID, and the message will be displayed if Hamster can find it in your local database.
FindString.hsc: Enter a string and a newsgroup, and the script will return all Message-ID's of messages containing the string.
Statsbot.hsc: Count the number of posts in a newsgroup, per poster per day, and post the results to a newsgroup. Don't forget to change the From-header and the X-Face-header, unless you want it to post with mine. :-)
