Hello sir, Sir to verify your achievement1 you should edit your achievement1. When editing it you will copy all of your work and paste it into a new content. The content should be shared again new comers community. You will do this because after 7 days the post expires. Mention my name @amjadali00 and also @goodybest. @goodybest will verify your post, mentioning my name is because if she forgets it I will ask someone else for verification.
And the achievement1 posted 23 days ago, you will delete it by editing it, copy it first to a new post than delete it.

I also did blender in the past, than I edited it. This is my post which I deleted
