I really thought I posted this the day I handed my ballot to a county dropbox worker. I guess not! I can't find that post now but now I also can't recall how to pin something to the top of my profile

Pinning is easy.
Go to your profile, go through your posts, find the post you want to pin,
At the bottom of that post is a menu of icons. Click on the rightmost icon, the triple-dot ("..."), then at the next dialog select "pin to profile".
Hope this helps.
