I would like to see all the GitHub issues I've reported (across all repositories). How can I do that?
Actually you can search for issues across repositories by including the
author:$author. Here is an example that searches for all issues created by me across all repos.
To take a look at all issues created by you on GitHub (either in your own repositories or in other people's), take a look here: https://github.com/dashboard/issues/created_by
Rob at GitHub said the 'issues created by you' page is broken by design:
Issues you've created in any other repository will only be available at the respective project's issues page. Our team is aware that this behavior can be confusing, so they are investigating possible changing this in the future.
