Custom Post Counter (forum selective)

[redfinite]

Hi everyone,

On my forum I have lists which people contribute to for adding different animal and plant species. These are confined to select forum and what I would like to do it give people another stat field which shows how many database additions they have made to ONLY those select forums.

A bit like the blog posts counter but forum only forums I select. Is this possible?

Or is there an alternative way of rewarding/displaying peoples contribution to a certain forum.

Thanks in advance.
