That's not exectly true. The MOD is created to limit user's sig length by their Rank. If you have not set a rank for new member (i.e. min. post = 0), then there's no way in limiting new user's sig length.
I have created a rank for Newbies set at 0 posts with the characters limited very low. It's still not working. If I go into one of my mods' profiles, it still shows her character limit as 255, the board default, when it's supposed to be 500, just like mine. Same with one of the Newbies I looked at. Hers was set at 255 & it should be 5. Also, when I created the new member, it didn't limit the size of the sig to 5 characters. It's still 255. That's the whole point of the mod, right?
I like the idea behind this mod. It looks like it works when you're in the ACP Ranks, but when you go anywhere else in the ACP like member's profile or to the forum's registration page, it's not working.
(P.S. I tried installing 1.1.0. It did something to the profile page. When you click Submit at the bottom, it gives you a blank page. So, had to uninstall it.)
