Can we rename this community to Antelope? EOS.IO is no longer maintained by B1. "The Coalition" is maintaining Antelope now. https://github.com/AntelopeIO/leap/
Long story short:
Yes, it's possible, and there are examples of other Stack Exchange sites that have been renamed.
The whole process and the requirements are not entirely clear, and I assume the first step is to get in contact with the Stack Exchange staff.
Previous examples show that it can take quite some time until the renaming happened.
