Where to report QGIS and QGIS-Plugin bugs?

I often find bugs in QGIS and its Plugins.

I would like to ask about this on the internet but I do not seem to find the proper place to address this issue.

Are there any instructions?

Answer

For QGIS, see https://issues.qgis.org/projects/qgis/issues

For plugins, see http://plugins.qgis.org/plugins/ and select the plugin, then go to the Details tab.

You need an OSGeo account to fill tickets. After creating that, go to your OSGeo user page. Then you can login to hub.qgis.org with the same user ID.
