I have another suggestion, if you don't mind... How about the ability for the IN page to be diffrent, based on which category the site is in?
For example, I'm running two sites,
TheICE.co.uk and
UnknownTales.net. What I'd like to do, in theory, is set-up a category for each of these sites, and when someone clicks on my button, it checks which category the site is in, and forwards it to the relevent page.
Of course, extended options to this feature could be the ability to define diffrent link-in buttons for each category, as well as the ability for the top-ten toplist sites data, based on category, to be displayed on a non-vB page (I might even try building that one myself).
Anyway, I hope you like the ideas
