Forum topics can extend to multiple pages, as topics are added. Is there an extension, that would permit (sub)forums themselves to extend to multiple pages?
I'd like to apply such an extension to, e.g., this forum: https://www.59plymouth.net/59forum/viewforum.php?f=22
Already a subforum of a subforum, it contains 40 entries (whose order I can control alphabetically, because they are forums, not posts). It could get longer. I could create yet another level of forum deferment - e.g., A-F, G-M, etc. - but, better yet if I could paginate the subforums after, say, 15 entries - just like topics within a forum.
Does such an extension exist, or is under consideration?
