We have chosen a new focus! Life on orbital habitats proved to be the most popular choice by ranked choice vote.
For the next four months the editors, and anyone else who wants to join in on the forums, will be focusing on this topic to add more details to the worldbuilding and expand our vision of what daily life within the grand megastructures of the sephirotics might be like. Everything from the smallest singlehab to the largest dyson swarm is fair game.

Happy Armstrong Day!

Fifty years ago today, Neil Armstrong and Buzz Aldrin first walked on the Moon. In the Tranquility Calendar, this is the last day of the year 50 AT.
When the Apollo astronauts stepped on the Moon, only the planets in our Solar System had ever been observed. Today, astronomers have detected thousands of new worlds. The Milky Way has hundreds of billions of worlds waiting to be walked upon; the future will hold many more 'small steps for Man' if we can find the determination to make them.

Important Announcement!
The Orion's Arm Universe Project Discussion Forum is now open!
All members of the Worldbuilding Group, Writing and Arts group, and 3D Modelling group are invited to join and continue the discussion there.

For the moment, we will be continuing to use the Yahoo groups for archiving, so don't unsubscribe just yet. Over time we will be moving the files, photos etc out of the Yahoo Groups and either onto the OA site itself or into the Forum, we'll be announcing that process as we go.
When posting on the new forum, please try to put posts in the correct area. Hopefully the structure is clear and reasonably self-explanatory, but do post any concerns in the suggestion box. Mods will aim to move threads into the correct area if necessary, but a redirect will be left its place so you can see where we have moved it to.
Any concerns, questions or suggestions can be posted here or (even better) on the new forum. Of course, you can also always contact any of the OA mods offline if you wish.
