MyBB Community Forums

Hello.

Could someone please explain to me what these templates reprezent? I don't understand what's their purpose since I don't know exactly on what kind of pages they're displayed.

In Forum Bit Templates:
forumbit_depth1_cat_subforum
forumbit_depth1_forum_lastpost
forumbit_depth2_cat

see http://docs.mybb.com/Admin_CP_Templates.html

Thank you.

I've allready checked the docs, but it only describes the template groups, not the actual templates.

hmm., strange. I am unable to trace their exact functionality! (still trying) {Edit: see this}

They have no functionality at all I think, emptied them all few weeks ago on test forum and couldn't see any issues.
