Freddie, my take on the etiquette of editing posts here is that it is fine to clean up a post for grammar when the post is new, but after that it does become a problem for the reason Tom mentions. You cannot edit without bringing your topic to the top of the forum. This is peculiar to Punaweb software.
A thread generally should not be bumped to the top unless there is something new to read, and people find it frustrating to look for the new comment only to find someone edited.
If you wish to change what you say after others have replied to the post, it is better to make a new comment explaining your revised thinking. Otherwise it is as if you are retrofitting an older post to reflect changes in your position that may be a result of comments. The topic should be like a conversation. We can't go back and "fix" something we already said. We can only go forward with a new comment.
For myself, I often see a typo after I submit and I do edit, but I do it right away. The only time I edit later is if I asked a question and it's sitting there and I have since figured out the answer -- so I edit it out so as not to waste people's time. The key thing is whether you have already received replies to your original wording.
I do understand the desire to correct when you are writing in a language that is not your native tongue, but bumping by editing is still not good netiquette. (Btw, you some of us can read le Francais. I can read what you write, but cannot at all compose in French.)
It does help that you explained French is your first language. [
