Where is the guest bar situated? which template, the one that pops up now and then?

Also which template holds the "Most Recent | Most Viewed | Most Discussed | Top Favorites | Top Rated | Featured | Random "

and which template above, is it that, I can modify?

For us that would like to develope the design of vshare can I also ask admin if there is a guide to exactly what is being called in which templtes and exactly which templates are controlling.

I have spent a week trying to find everything, & still at it.
Thanks
