/user/@bob:bob.net should start a DM with bob

[lukebarnard1]

Required to do "start DM with RiotBot" button/link nicely

i agree we need a URL for this, but /user is already used to pull up the MemberInfo for bob, i think. So prolly needs a different prefix.

Another alternative would be to add a query parameter to the link, e.g. /user/@uhoreg:matrix.org?action=chat (see also matrix-org/matrix.to#22 for some thoughts on the matrix.to side)

Also, it should probably have some sort of confirmation screen before starting a DM, otherwise someone could post a message saying Click <a href="/user/@uhoreg:matrix.org?action=chat">here for free money</a>!, and flood me with invite spam.

I believe the plan is now to move forward with this.

The behaviour as I understand it will be:

• click /user/@uhoreg:matrix.org?action=chat
  • if the user is not logged in, show choose a mxid
  • if the user is logged in and has no DM with uhoreg, prompt them asking if they'd like to start one
  • if the user is logged in and has one-or-more DMs with uhoreg, prompt them asking if they'd like to use one of the existing DMs or start a new one

Are there any complexities introduced by the user navigating straight into https://riot.im/app/#/user/@uhoreg:matrix.org?action=chat (i.e. not clicking a link whilst already operating within the app)?

• if they're not logged in, can we just show them the choose a mxid dialogue? On top of a blank background, or the welcome page?
