Please do no explode large tnt in your constructions. Such activities tends to crash the server, stressing the host machine and ruining it for other players. As mentioned in What would you want as a new FTB server?
, an option is to retain the world and just move it to a new host. You are making premature assumptions if you presume that the world will be replaced.
As for your pets, that is your choice, but we will be saving the world intact when the server is stopped on Wed. While Mo's Creatures may not be everyone's favourite mod, no possibility is completely excluded until the decision is made about a new host and whether that will include a FTB server.
For those who didn't attend the discussion, the Admin team has made the decision to shut down the FTB server out of politeness to Exe. He has put a lot into the division and the FTB servers have cost him a lot more than any other world. While he has given us some time to find a new host, the Admin team has decided that it is rude and disrepectful to continue to run the large money drainer for longer than we need to. Hence, we are stopping the Mindcrack server but keeping Frontier running for a bit longer.
Yes, the division was not asked for its opinion about this because it is an administration decision. We had to make the hard choice, just like Exe did.
