I was using the old shoutbox 2 from like 2006 or something. it used a flat file to pull data to the box for the 50 posts. It had almost 0 server load.

maybe this will help you for the next version.
However i can't confirm it but i think that version is weak on security. Have had to injections to my server from vbulliten even after the latest upgrade adn the only thing i can see that is still not updated was this old hack.
So be careful with any code you use from that link if you do.
Anxiously await update! the secial characters fix didn't work for me.
i even tried all this
Code:
var value = document.getElementById('body').value;
var amp = "%26";
txt = value.replace(/&/gi, amp)
var params = 'body=' + txt;
i checked the DB too and it never makes it. Every character works except for the ampersand... no matter what i try, even escape().
irritating!
