Is the Fit to talk user here in the forum? For he absolutely can post it on the Begginers&help board, it is very informative.
I think he should be the one posting it as well as the link to his blog, from the post is coming. Also, all the Fit To Talk users might tell the whole history of the thread, I mean, if they come from some sort of corrections in Fit to Talk, I believe they should talk about it.

For instance, the user makes the thread starting with:
"This post has been corrected by the Fit To talk project users in order to make it more comprehensible and well-written. If you want to join the project (the link)"
And, after that, he can copy his/her own post.

I don't think it can be seen as scamming, for the Fit To Talk project has no money involved, but the will of helping others to improve their skills and to use them in here, so we can put a small seed in here, perhaps, and those truly interested in creating some good stuff will know where to go to learn more about the English grammar and so.
