If you really want to reduce bandwidth and server load:
Open a new window when a user clicks a link in Recent Changes.
If a user follows a link and returns to Recent Changes MS Explorer
reloads the page (at least with default settings).
This may be lame behaviour by MSIE, yet it is a fact we have to live
with.
I brought this up once before and the reaction was: there are better
browsers so dump MSIE. My point is: MSIE is still a de facto standard,
90% of the Wp visitors use it, so we better deal with it.
