I've gotten the thumbnail counts set in all other modules in the site however I cannot find where to reduce the thumbnail count in the Groups section that is located in the User Profile.

Where do I adjust this thumbnail count? I want to adjust by -1/

Hi Jared,
It is very easy to do.
Just insert below lines at root/modules/mod_community_groups/mod_community_groups.php line no 33

if(count($groups)){
    array_pop($groups);
}

That's not what I was quite looking for as this method reduced the thumbnail count across the entire site and I just need the count reduced on the members profile only.

I will try to create an override for components/com_community/templates/default/profile.groups.php and see if that works.

Just FYI for your own knowledge base - the override was successful.

Line 27

for($i = 0; ($i < 15) && ($i < count($groups)); $i++
