Also why doesn't it show the my posts made after 11th April ?
That's the day they imported the current database into the Beta to have content, it's not synced to the live forum.
Ah I see. But where did they come up with the magical number of 1505?
Edit : There are no ranks on the new forum?
Edit 2 : What about personal messages? Wont they be imported?
1505 is just a miscalculation/placeholder for your post count, everyone has absurd values, it also seems everyone is "HERO" as of now which I'm sure will be fixed with time
