Has there been a change behind the scenes to how the posting rank is calculated, or have I just reverted to being a Junior Poster with 900+ posts for no reason?

As know there are people at hjgher ranks with less posts.

Are you sure it's not set as "Junior Poster" in your profile (User Title at the bottom)?

^^ Seen this alot lately, how can you guys be appearing lower than me with only 300+ posts?

Did Dani make a change allowing more people to edit their user titles lateley then or something?

Yup you were right prit. Must be a defaulting behaviour though as I didn't add it

Yes.

So everyone can change their title or is there a post limit?

All non-newbies.
