Since this is 3 weeks away I haven't confirmed any speakers yet.
If the meeting receives enough interest, then it will grow. There are other groups such as Save Passenger Rail and a Living Wage group, the overlapping interests can help to boost this new group.
But don't worry, some people are organising on behalf of Renters United. They haven't announced it yet, which annoys me. Let's hope it happens before the election and not after! Stay tuned. These other people are a few steps ahead of me. I'm done with organising, I'll leave that to the pros.
