Can anyone help with the following probs I have with Shoutbox 3.0/

1. How to hide the 'Erase' button from anyone but an admin.
2. How to lock Auto Refresh (ie so it is automatically on - it's my own server so don't need to worry about upsetting an ISP here! Have tried a cron job as per someone else's suggestion but it doesn't work). I want the page to auto-refresh for everyone at a given time interval.
3.(not mega urgent but would be nice) Get rid of the IP addresses displayed on mouse over for users. ie if you mouse over a username in the window EVERYONE can see the IP address, not just me. This is probably a permission issue buried somewhere in the innards but I'm buggered if I can find it.

Anyhelp would be massively appreciated!
Cheers
Si.
