Welcome to the community Marcel. Deciding to make an introduction about yourself is good idea. Steemians love to communicate with people who has real identity especially that the platform involves money as rewards.

This is not required but is an advantage. Can you post a picture of you holding a piece of paper with the word steemit, yourname and date. You can just paste it the comments to avoid making another intro post.

If you have facebook profile (I believe you do), kindly share your profile link as well. By doing this, you will be a verified steemians.
