Maryana, this was much after that campaign (that was in 04/2011 the spike
was in late 05 - early 06/2012).
It has been pointed out in ptwiki that all these pages are in the sidebar,
checking out the other pages from the sidebar only the main page, the
contact page and the random page link did *not *have the access spike, all
other pages had a similar spike.
I vote on a secret experiment :)
