It should be possible to mention speakers/sessions within project comments

[anishTP]

Context

Project comments are the main source of interactivity within a project. A project can have scheduled sessions that are organized into multiple tracks. The audience questions and comments for these sessions are currently added in the project comments. There is currently no way to tag/mention a session or a speaker to provide context to an audience question or to notify the user(s) the comment/question is aimed at.

Solutions

Mentions
A user mention feature that sends out a notification whenever a user's account handle is mentioned in a comment. All subsequent replies in the comment thread will be notified to all the participants in the conversation. This feature implies that account handles are mandatory. Currently making an account handle is optional for users who log-in via an OTP.
It is also easy to loose context for the users who are reading past comments as all the comments are centralised in one place.

Session comments
Users should be allowed to add comments under sessions to provide a clear context and also to notify the relevant users. Currently sessions don't have a comment section that enables session specific interaction. The session card is mostly populated by the proposal text. This text can be made into a collapsible section to make room for user comments below the session video.
