Forum logo redirect to current category instead of site index

ImWithStupid

I am trying to have when a user clicks the logo of my site for the page to refresh on the current category they are in, instead of how I have it set up now where it redirects back to the site index.

I'm not sure what code I would put in the master template (I'm using .tpl) or somewhere else in the forum files to get it to do this.

Thanks for any help.
