There seems to be slight confusion about this and I guess I didn't make it very clear. The discussion prompts (posted on Mondays) are taken from the mini meta fests prompt lists. The Monday discussion prompt is then picked pretty much at random.( Full prompt list )
This is mainly so I don't have to come up with a discussion prompt all on my lonesome. If you have a prompt feel free to leave a comment. They don't need to be femslash, just female friendly.
Edit: Remember this is a prompt post only! If you see something you desperately want to respond to you have two options. Option 1 (and my favorite): Make a new post to the community and lay out your thoughts. Option 2: Wait for me to use it as a discussion topic. Option 1 is clearly the better one, but you can wait if you want.
