Hi Nadiak,
It's under the same place...the UCP(User Control Panel). The profile used to just show you things like your statistics(number of posts, etc.) To edit your profile you go to https://www.doll-fan.com/forums/user ( there's a drop down arrow next to your forum avatar ) then to the profile tab in UCP then "edit signature".

No problem...the deal I think most are going to have issues with is that there is a forum profile(UCP) that controls specific settings for how you want to the forums to operate and there's a profile for the rest of the site. I think some previously navigated the long way around by clicking on their forum profile and then going to the UCP from there where others always just went straight to the UCP. Now that when you click on your username it takes you to the sitewide profile instead of the board profile some are getting lost. It's all what one was used to and how they navigated.
