How to block unwanted group member?

Can a admin block a member from a group if he/she is not showing up on the member list but posting comments?

• I really need this person removed and yet to find an answer of how to remove them.

• Answer:

  You'd want to check your groups message settings and be sure only members can post. You also might want to have moderated new member settings to prevent unwanted posts. Those settings are **management- under group settings click messages- Posting and Archives (Edit) <-- click the edit *Who can post = members *Moderation = whatever your choice is- but any choice only affects those who join after this setting is made- if you want to moderate members that are already there, that's in a different area. If you want those instructions, just ask. Moderated members stay moderated until you change it per member. Click save change when done **You can ban any Yahoo ID or e-mail address by going to --> members list (left side of honepage)- you will see upper right Invite People | Remove | Ban | Download | Export click the ban tab- enter ID or address and click Ban Members.
