Invite URL questions [delete name, shorten, nick-based discovery, business card]

Hello all,

I am a new Delta Chat user and it fits my needs in so many ways, but I will list them another day.

Question 1: When I make an invite code it put my name at the end of it.
Is this required? Can I cut that off and share the modified URL?

Question 2: is there an official URL Shortener?

Question 3: is there a simple unique username I can give to friends or put on my business card, etc?

Thank you to all involved for this great App!!

Yes, you can cut off the name, but your peer will see your name again after joining. So, you should preferably pick a name that is not compromising for you in the first place when creating a throw away profile for invitations.

Shortening the invite link would defeat the whole purpose of providing cryptographic material out of band.

Centralized usernames would defeat the purpose of the decentralized nature of DC, open up a centralized actor to metadata collection and could MITM and deny people making connections.
