When there's less than 100 blocks, every block seems right. It's a bit much this far out, but it's also helpful to post often to get noticed considering there's no algorithm. I'm of both minds on this one.  

 I might change to sending the message every 6 blocks for now and then when less than 100 blocks, send for each.  

 A happy medium, just like Goldilocks's coffee 

 Done!
