This is the position to post all your built up excitement for getting to a post point of pride.
This will save forum space, and it will make everyone happy! I also suggest throwing shout outs. It will be like a special award show. But with no awards. So if you have something to yell in excitement that relates to post counts, just search up the official "i got a 1000 (etc) posts!" thread on the search bar and post your happy scream of joy!
