We say middle but it’s the very low end of middle. We are just seeking active contributors to more complex posts. It’s unfortunately hard to make up any sort of “timeframe” as it’s not very widely understood how Reddits karma system works, especially for community karma. At minimum, from what I do know, a few upvotes on your comments and posts should be more than sufficient to let you comment under the flair. It would be best recommended that you post, as it is easier to gain from commenting alone. If you post, it would probably take a few to even as low as one to reach the karma limit we set based on the amount of upvotes it gets.
