Not sure there's many reading this from those subforums, but actually genuinely curious if anyone else does this to perhaps improve their fluency in other languages. I have tried to post in the past, usually erasing my response due to anxiety of getting sentences wrong - honestly curious if anyone in those subforums would care or mind?
This thinking is as a user, not as a local moderator.
I see people posted in global / English boards even with bad English so can you do the same in French local board?
I believe you are allowed to do this with at least acceptable, understandable French writing skills. Of course no need to habe perfect or proficient French. In the past, theymos shared his opinion that if a member can post in English as a second language, not good in vocab, grammar but if content is understandable, no big problem with him.
I think again it can be applied for your posts in French local board too.
Another issue is pointed by Halab. If this style is exploited to fill campaign post quota, it is wrong and will be detected. I don't imply you want to do this.
