v3.6.8 Template location equivalents of the new v3.7 ad placement templates

[JamesUK]

We're trying to include an image that's displayed on almost every forum page.

We'd like to integrate it near the bottom of the page so it's not too obtrusive, but not as far down as the footer.

Ideally we'd like it inbetween the list of forums and the 'what's going on' panel on the front page and above the 'quick reply' panel on each thread.

Could someone kindly point me in the direction of which templates I should be looking to poke my code into?

It seems there's perfect templates set up in V3.7 for this, but I'm not in a position to update from 3.6.8 until after we get this style update live....

So what I'm after is to know where to look for the equivalent positions for the following 3 new ad position template positions are within the 3.6.8 templates:

ad_forumdisplay_afterthreads
ad_forumhome_afterforums
ad_showthread_beforeqr

Doesn't have to be exact, just a rough idea of where I should be looking would be really helpful as I'm totally lost :s

thanks,
James
