actually those checkpoints secure the blockchain (see
https://bitcointalk.org/index.php?topic=194078.0) to prevent additional chains with really fast asics
now the chain used by ccex and dutch-mining is off of the "official" one, but thats another matter
if one wants to sync to the official chain i suggest using the addnodes provided by nova
the other way round use those by ccex
It's too close to xmas to be using that language man :p just gave me a OMG we got AA batteries but needed AAA. lol.
