@theartguy BTW, do you know the secret for how to fix it if you accidentally do that?
@theartguy Easier: just write over it with a regular whiteboard marker and erase. Apparently the whiteboard markers just have regular permanent ink plus a solvent.
@peterdrake Anything with rubbing alcohol, including hand sanitizer, if I recall.
