I think all of these ideas are great, and would really bring FH more to life in a sense.
With the biomes, I do believe it'll give the roleplayers of FH more of a variety of places to rp in, especially the mapless rp groups. What Bawfle said basically explains my feelings on that idea; I think it'd really do wonders for FH, and I'd love to see it happen.
With the newsletters, I definitely agree with that idea. Having a secretary-like staffer to specifically write maybe monthly or even just seasonal newsletters to keep us all updated, as well as handle other administrative things would really benefit the community.
I definitely agree with the other things you've brought up here, they're really great suggestions, ones that I hope will be taken into consideration. Thank you very much for sharing these ideas with us, Deu!
