About This File
Converts link forums into proxies for actual forums, allowing post information, post counts, etc from the destination forum to be visible when viewing the link forum.
Note; only works as expected for destinations that are a Forum (not a page or anything else). Does not have much in the way of input validation.
To a front-end user, a link forum can be made nearly indistinguishable from a normal forum.
Performance Impact
This causes 1 extra query if there are link-forums on the forum-list page.
