Some bugs may have been left open even though they've been fixed. Others don't have much information.

Go through the list of open bugs (status = new or incomplete or in progress https://bugs.launchpad.net/sahana-agasti) and try to reproduce the bug:

If the bug is gone, add a comment to the ticket with what you did and "resolve" the bug as "invalid". (The submitter can still reply and reopen the bug if they want.)

If you can reproduce the bug but the description isn't clear, add better "how to reproduce" instructions and change status to "confirmed"

If you can't figure out what the ticket means, add a reply that tells the bug reporter what info would be helpful.
