You’re trust level 3 now, BTW. I just checked your .json.
Now I wait for mine. =(
EDIT: Also, I just checked, there are a few other users with Trust Level 3 who have well below 20,000 posts read. I do not believe the 20,000 posts requirement is real.
For example, @Minky has Trust Level 3 with only 16k posts read.
