HELP!!!!When backing up my sites this morning,I found one of my sites had suffered a Spam attack, whereby upwards of 400 comments were posted in the K2 comments section. Whilst this is more of a nause than any security risk, it leaves me with a question;Does anybody know of any good components to add extra security to my sites??  All Comments will be welcomedI have now (should have done it in the first place) made the K2 comments for registered users only. I have advanced registration in place and joomlawatch which is "supposed to" stop them.Thanks in advanceJasper
