LOOKING TO START A MFP GROUP

I am looking to start a MFP group. I started one before but had no idea what I was doing. I am looking to start a group WITH someone who knows the ins and outs of running a group. If you are interested and can explain why you would be a good fit, message me!

1) I want this group to be ORGANIZED. I do not want just anyone posting threads... I want the threads only posted by the admins.(I dont know how to lock threads, this is where I would need help!)
2) I would like a group where there are weekly challenges.
3) Also, the group would do weekly weigh-ins.
4) Members must have a goal!
5) I want to limit the number of members to 150. (I dont know how to do this, this is where I would need help!)
6) If members do not interact after a week, they will be removed.
7) I want sub topics to include: intros, recipes, and general chit chat.
8) Looking for a catchy name and photo for the group.

If you can help with these things, you must message me! I will not get notifications if people respond to this post.

Thank you!
