In our Amateur Radio community, everyone has a licensed call sign. However while many may use that call sign as the first part before the @ symbol of their email address, there also many who have other email addresses. We require that IDs are call signs. So if I send and invite to someone who has their call sign in the first part of their email address - that works fine. But for those who do not - I am stuck. It appears that I cannot specify the ID that an invited person will have upon responding even though I know what it must be. If I am not missing something, this would be nice to have.
