how can i delete my posts/questions in this forum?
how can i change/delete the screenshots i added in the question?

This is really frustrating. i just asked questions and tried to delete my attached screenshot but there is no option to delete the attached screenshot and delete the old questions i asked here in the forum.

Hello,

Specify which items do you want to remove and we will delete them from the forum.

Kind Regards
