I cannot seem to find a post on the F.I. forum (A question, not an answer).
My online page only shows me the answers I have given.
Is it my computer?

your posts are all here : http://www.dafont.com/fr/forum/user.php?user=444696

Forum moderators remove crappy pictures (stretched, fuzzy,...), so maybe yours was in one of those categories.
