Thank you for questions!
1. The tweeter was created was a community member and currently is not supported and I don't have access to it. We can create a new official twitter.
I think you should do it right away and try to rebuild the community since you are the one in charge, if a community member loses interest in a project and he holds one of the social accounts of the project he can use that account for another project
3. We would like to make new exchange listing for coin on BGL mainnet, but currently we don't have a person to arrange that.
Doing a bounty campaign for this will do, BGL used to have a signature campaign, and it's a long campaign I think its time to launch a new one to generate interest for old and investors
4. We have communicated with CMC with all the links included, probably they are still processing or mb that is not on their priority list.
This project is unique its hard to see a project like this go to waste and the community is still supportive of the project
