1. Can U make it where we can have gifs as our profile pic
Assuming you mean, an animated gif, it is possible, but might also be too distracting.
2. Can U make it where U can friend people on Kidztalk like U do on kidznet?
You can currently follow users and topics by clicking on the star icon on a profile or post. We will look into friending users.
3. Can U make it where we can and a short biography to our profile if we want?
This is now in development.
4. Can U make it where we can edit our private messages?
It would be very involved, but is possible. You can always just delete a message now and send a new one. Mobile phone text messages cannot be edited.
