Months ago, in 2018 or 2019, one forum member asked that will his posts be deleted or he get banned if he makes posts in French local board just as to practice his French-learning process. He was learning French, I meant. I remembered Halab said it is fine if his posts are understandable somewhat.
I can not find that topic but hope if Halab see this post, he can help to spot it.
If you want the quotes, here is the quote from theymos regarding posting in local section and how rules are enforced.
The local sections are primarily divisions based on language. The moderators of each local section are allowed to set different standards for how fluent your posts have to be, but you should never be excluded based on residency/ethnicity/nationality.
Here is the quote from Halab regarding how he will be enforcing things in his local board.
Yes, red tags were generously given in the french section for very bad translations of ANNs when there was no moderator. Now it's easier, I delete

You can come and discuss or ask questions in the french section, it's not a big problem if you use Google Translate. But, if you come to make your posts for your signature campaign, it's going to be more complicated.
