I think this is more to do with the site than Lemmings games. I'm pretty sure one of the global mods can move this over to Site Discussion.
Anyway, this reminds me. As a Moderator there are a few buttons on this forum (Such as Split Topic) that I've never touched before and would like some guidance with for the future. A video sounds like a great idea indeed. However, as WillLem is not an admin, finding someone willing to teach about the extra buttons is more tricky. If there are any moderator guide videos out there then please let me know.
