just wondering because of the new dance link business can i just put the [/dance=icarus] under 'url'? would that work?

You can use the old links,

http://subeta.net/explore/masquerade.php?act=invite&user=######

The # is where your user ID number goes.

For billboards, that link doesn't expire.

oh all right, awesome :) thanks for the quick answer!

No problem. :)
