Tag mr david emagun

I'm happy to help! However, I need more information about who Mr. David Emagun is and what you would like to tag him for. Could you please provide more context or clarify what you mean by "tag"? Are you trying to:

1. Mention him in a conversation or post?
2. Share a message or update with him?
3. Request his attention or feedback on something?
4. Something else entirely?

Please provide more details, and I'll do my best to assist you!
