Yes, you must write a new post. You post it in the Newcomers' Community.
Heading: 1st Progress Report
And then you must include the following in it.

Please, don't use these points as a template - templates are so boring 🥱 - we're interested in hearing about your experience so far. You could use some of the following ideas as prompts...

A summary of the communities you've joined, why you've joined them, which you like the most and why.

The topics you've been writing about.

A list of key people you've interacted with. An introduction to the people who have had the biggest impact upon your experience so far (NOT an opportunity to tag whales) and the unexpected relationships that you've experienced.

Your most successful post - Why do you think it was successful?

Other observations - What have you learnt and discovered that you weren't expecting to.

Your plan and expectations for the next month on the platform (please don't mention growing your account!)

Good luck!
