Unfortunately, Discord does not yet allow for per-server avatars or playing statuses. If you want to change Circle's username, simply set a nickname.
Absolutely, check out the General plugin.
There could be a few reasons Circle isn't responding to you, so let's go through some common ones before we get the team involved:
Does Circle have permissions to read, speak and embed links in that channel?
Are you using the right prefix? (You can mention Circle and run the prefix command to see your prefix.)
Is that a command?
Is the plugin disabled?
If we haven't narrowed down the issue, please contact us so we can set Circle straight!
We do not and have never stored your IP or other data at all. There is no possible way for anyone to attain your IP through Circle. If you have specific privacy questions, please see us in our support server.
We flag accounts based off extensive amounts of evidence of suspicious activity. If you would like to get removed from this list, or see the reasons behind your flag, please see us in our support server.
