This question already has an answer here:
Today on SO I reviewed question for reopening. The question did not warrent reopening IMHO, but after selecting that option, I went back and realised I had been one of the original people that contributed to closing the question in the first place.
Had I realised this earlier, I probably have skipped on this reopen vote. The reopen queue is empty most of the time anyway.
I would prefer not to get in this situation, so I think SO should filter the original 'closers' out for reopen reviews. If that is undesirable, then I would like to have an easier way to notice this than to scroll down to the bottom of the question to see who originally closed this, especially since that info is not there if you look at the revisions tab of a question.
A way to improve my memory would be a nice option, but less practical.
