I created the following userboxes which proudly proclaim "Yadda has a User Page for the user. They're sort of obsolete now because of SUL. Formerly, you had to register separately on each and every Wikimedia project. Now, once you start a global unified account, as soon as you edit on any project you are registered for that project, so making a user page on another project is much easier, although the user pages themselves still aren't intrinsically connected, which does leave these templates with some value.
I created the following userbox. It used to exist in template namespace until the decision was made to put user identifying userboxes into userspace rather than template space, so it eventually made its way back here, to my userspace.
{{Userbox
|id-fc = black
|info-s = 8
|border-c = blue
|info-c = lightblue
|id-c = turquoise
|id = LDS
|info-fc = black
|info = This user is a member of <br> '''[[The Church of Jesus Christ of Latter-day Saints]]'''.
}}
The following userboxes were created for Leave No Trace.
