I CAN'T ADD NAMES TO MY GROUPS.  I HAVE TRIED MANY TIMES

I can add people to an existing group, but I can not, for the life of me, figure out how to create a NEW group.
Is this anyway that I can merge 2 contacts manually?
The "Clean up contact" function doesn't seem to work properly
And how can I add many people to a group, without doing it one by one?
Ever since the format of the contacts went to the red simplified version, I cannot find any way to see who is in my groups, or to manipulated them.  I can only add new groups.  How do I get back into my groups?
If I add John Jones & Betty Jones to a group that I created for christmas cards and I put them in the group as Mr & Mrs Jones, it changes them in my ALL contacts. How do I create a formal contact list for mailing purposes?
I have finally managed to create groups for my contacts with help from this forum.  However when I try and email a group of people I can do it for a small group of 11 people but it won't let me send an email to another group which has about 200 people in it.  Is there a limit to how many people one can email at once?  Thanks

How do I delete a contact from a Group without actually deleting that person from my contact list?

 

How do i go into a "group" and see the individual contacts?
Groups seams like in the memory: when I start printing group in the new email it's there, but I can't find it to add or remove a person.

When I am sending an email to a group of people, I do not want everyone to know who all will receive the message.  Thanks
