Hi: I have posted a post in math dot stackexcange dot com which includes an image and your site said that I could not post and image because I should have reputation above 10 to do that. But according to you my reputation was above 300 at the moment I posted.
So, I want to post another image to see if the error (in case it is an error) repeats itself. Can I post a test post in math dot meta dot stackexchange dot com? And in case I can what message should I include in the post so that other users do not complain?
