[geeklog-devel] Forums hack

I've corrected the database for the offending post - the user had
entered a <meta refresh tag as his name but since there is a field size
limit the URL as Joe noted was not correct. The script does pass the
post var thru COM_checkHTML but looks like this tag was allowed thru.
I've banned the IP and moved the post out of the public forums but there
is nothing else much in the content other then the posting IP of interest.
I will do some more testing with what he used as his name.
