Tag variable: any chance to include %%posttotal%% ?

Hi there,

I was wondering if it was possible to include in any way a tag variable that would be called like %%posttotal%% that will replace with the current number of posts in that category/taxanomy.

My goal is to be able to write in the page title:

“Find over 35 posts in this category”

Thanks
