Hi, I want to make a feature request: Related Topics based on title.
This will make another topic that similar be recommended to the visitor, thus increasing the discoveribility of contents and user retention in the forum.
Maybe this is better as an addon.
I think these is more addon stuff since its not that useful for every forum, specially small ones like most of Elk's community.
There is already a mod or two in smf of which I think you can convert, at least for personal use, for that matter.
Depending on where it gonna show, I think you could get it done fully hook as well.
