On occasion, we have to uproot and close a proposal which has been too slow at gaining support to remain viable. Typically, there is nothing inherently wrong with the subject being proposed, but after 4 months in Definition or Commitment, you have to determine if the proposal still has the support it once had.
Do you have a community ready to build your site?
We generally expect proposal authors to have access to a community to help build your site. Area 51 cannot find that community FOR you.
If you have access to a healthy, enthusiastic community needing a Stack Exchange site, feel free to restart the proposal and try again.
To build a successful site, you'll definitely need more of a running start to make it viable. The only way to make this work is to go out and actively find a community to support your site. If you find a health, enthusiastic community to build your site, your efforts should go quickly the second time around. If not, it wasn't meant to be.
Good luck!
Note: This is a general announcement. Please bring any specific discussions or comments about your site back to your proposal page.
