The first one of those is a good name, which should:
- Be somehow related to worldbuilding;
- Have the relevant .wordpress.com (or other equivalent on another platform) domain available.
(You may also want to propose a tagline.)
The second one of these is a schedule. Here I'd like some more input from those who volunteered to contribute in the last post: how often can you commit to writing something? This is not an absolute commitment - a few missed days won't matter too much - but we should be putting content out regularly, so we need to work out how to do that. Tell us how much content you can commit to writing, and we can work out a schedule.
Note: There is also a discussion about platform to be had, as Monica Cellio said in the comments. If you wish to chip in on this, please use this chatroom.
