My reputation just went down by 15 points for some reason. I think my answer was accepted at one point for PSU power cable length, and will my graphics card fit in my case?, but now the other answer is accepted.
Did that actually just happen? If so, when did that become possible? Or has it always been possible and I just didn't realize it?
Losing a bit of reputation doesn't bother me, I'm just curious what the heck happened and if I'm imagining / seeing things.
OK, so it looks like I didn't realize the OP can change accepted answers at any time. No big deal. I guess the only way to know this has happened is to notice the missing reputation and notice that one of your answers is no longer the accepted one.
