Anon, you have greatly misunderstood the purpose of this forum and what we do.
1) We do not write letters for people.
2) We do not send invitations to people on your behalf.
3) We are not your adminstrative assistants.
Here is what we DO do: Review letters/invitations that you have written to help you with the grammar.
If you write the invitation, we will help you make it better. Then YOU send it to people, not us.
Never post the personal contact information for the people you want to communicate with on here. I know that I would not like to see my home address, phone number, and mobile phone number posted on a forum like this, without my knowledge and without my permission. I expect they do not want this either.
