I don't see your Shout Box, but you always want to be careful.  Never give out Owner privileges to people you don't know, same goes for Admins. and Mods and Global Mods.  You want to keep your site as safe as possible.  But those are from internal hacks, like someone banning you from your own forum.  That sounds like someone might be messing with you, maybe a friend trying to pull a joke, but that isn't a funny one at all.  To be honest with  you, if someone is gong to hack your site, they are going to do it, basically no matter what you do.  I have a friend who's forum was hacked not once, but twice, and it was a mess.  Her site is quite large.  A hacker can hack a site no matter the size of it, small or very large.  Just keep a close out on things, track IP''s and just protect yourself.  I would advise making only one board viewable to guest rather than your whole forum.  Good luck and keep us posted.

That is kind of a confusing one... for you cannot have any SOFTWARE to do that... and if there was... the software would be YOU! You would have to check the security, by reminding them to change their pass words frequently ONLY IF your forum is in the THREAT of being hacked.

Thats MY Advice!

The right click copyright code doesn't fully protect a forum from having it's content taken.
Anyone with any knowledge of a forum can still copy stuff.

Can they really get hacked? wow i didnt know that.

Hacking usually takes place by people that you make Mods and Admins that have no background with you and you don't really know that well.  Even between friends you can have a falling out and one will say to themselves:  "Well, they think they are so smart, watch this".

Always keep full control for yourself, never give out your password and only give permissions to someone you know you can trust.
