General Comments
- Safety is very important--a user should always be certain of the level of privacy they're communicating with
- Need connecting with people to be fairly easy to be adoptable
- Most (if not all) actions will be preformed in private (probably a very clean, quiet environment) (according to the user in the second interview).
- Where possible, tasks will mimic those in other chat applications. Where unique, tasks will include a short help text. In most cases, new users will be taught the basics by the person who introduced them to the application.
- The frequencies are based on estimates given by the user in the second interview.
