How do you send someone a alliance invite?

Thank You

Hi can someone answer my question?
How do you launch interplanetary Missles?

Please tell me how to launch these?

Another cool thing would be to let each person make one variety of a ship that only they could build or use depending on their level and it would obviously have restrictions also if they would want to make a new one they would have to delete they all of the old version and make the new one.
