What are the character limits for each of the following types of posts?
  • Forum post
  • Image description
  • Comment on image
The reason I ask is that I’m going to publish a long review of the new movie on Reddit tomorrow and am thinking of reposting it in the Pony Discussion board over here (since both sites use MD now).
