I stopped doing them because I was nowhere near 500 to cash in. I am not sure what they are going to do, either zero out my account for me to start over with another partner or carry over what I have earned to a new partner. Hence, that is why I did not do any more invites.

If it is the former, then I am done with them, if the latter, they I will resume responding and will also be glad to be rid of the Skypesos. United would be my favored course.

In addition, since e-miles is owned by e-rewards, I would not be surprised to see Delta disappear from that entity, as well.
