hi guys, ive seen a couple of hacks around, welcome panel etc but they dont seem to do what im after.

in a area on my page that i select (the whole header in my normal site is an include) i want to display the number of users that are online on my forum.

all i want is a message along the lines of 'XX active users, register now!' with register now being a link to the signup page.

can someone help me code this up? or show me what to include and what code i need to make the data display?

thanks in advance!
