Hey there :)
I stumbled upon this site while trying to find ways to cease my cracking.
My fiance is driven nuts by it, and absolutely can't stand when I crack my toes. All I have to do usually is just bend them in and they'll crack. I used to have to put pressure on them but now I can do it freely.
I also crack my knuckles, back, sometimes ankles (usually only my left one when it gets really stiff), shoulders, and neck.
Welcome, you're not alone. I used to drive my husband nuts with it, but we've been married 14 years now, and he's used to it.
