Extend number of groups listed on each page?

[kevinh]

I'm using a limited number of social groups (23) and I want them all to display in the first page of the list of Social Groups. (Currently any groups after 20 are listed in a second page)

What do I need to change to make say each page display 25 groups rather than 20?

There doesn't appear to be a setting for this in AdminCP so I'm assuming an edit is required.

I'm assuming it has something to do with $pagenav

If this is correct, what is $pagenav and how do I edit it?

Thanks,
Kevin
