How To Make A Submission With X
One of the ways to make a submission is to post the proof picture to X.
If you wish to make your submissions this way, here's how:
Post your submission pictures to your X account. See here to know what should be included in the post.
Copy-paste the link to that X post to the 'X Post' field and press 'Submit'.

Please note, that you may not delete the X post afterwards.
If you wish to not make your submissions using X, read here on how you can make submissions through Direct Upload.
