General questions that may require clarification/how to proceed

• In the COC and reporting security bugs section, how do contributors report unacceptable behaviour/security issues. Right now I have a send to [email] but no email address for it to be sent to.
• The slack channel link I referenced in the file, can you share one that does not expire? I am guessing the one I copied from my end may have an expiration date.
• For the recommendation order, is there a preferred order than the one I have currently?

Kindly let me know if this aligns to the project's needs/ the cprrect way to reference appropriate channels.

@Honyii The Slack channel is fine
For the email address, please use support@union.ai (I know, it should be security, but it will get to the right person)
For the DCO thing do this:

git rebase HEAD~N --signoff
git push --force-with-lease

(where N is the number of commits in the PR)
