No need to get the hump: if you don't have time to read the rules of a group (there are only 5 rules in Freewriters and the Cross-posting one is number 3) don't cross-post in it.
You are welcome to "freewrite" in the freewriters community. Cross-posting is not the same as writing a post in the community.
Feel free to post directly in the community.
We look forward to reading your posts.
