Question about a little change to default generator settings

[BakermanLP]

Hello,
we would like to change some minor things in Fun World Generation for our new modpack. This would be the default generator setting, because we need "SKYLAND#0" as default.

Can we do that and redistribute that? We won't get any money from that, also we don't use adfly or anything similar.

We are asking that, because we haven't found any licensing information.

Thanks for your answer

Michael (aka BakermanLP)
