I was reviewing some of my older questions here in GIS Stack Exchange. I found some of them to be off-topic due to new version of software (e.g. error-using-grass-v-net) or for being not-reproducible (e.g. georeferencing-arcmap-10-2-trouble-with-deleting-control-points).
An attempt to delete them raise an alert saying: that it is not advisable to delete question with answers. Seeing the close option, I've decide to vote to close them and let moderators to decide on this issue.
I therefore would like to ask about guidelines for closing / deleting my own questions. Should I just delete them if I'm convinced they are irrelevant? Should I vote on closing the question, and in that case should I also raise a flag on it?
