There is a 'Characters' menu on the bottom red bar, it should list all the characters. Let me know if you can not see links to all 6.
In order for us to be able to see the contents of the sheets, you all need to mark the grey 'note' icon that says Add to Library on your
character list.

Red means others can see the sheet.
You can also add a small portrait using the Change Avatar link (top right of sheet). It does not need to be a picture of the character, but having something distinct displayed with your post does help us keep track of characters.

Current party' thread
Good idea, everyone should be able to edit that post (even though it is not a real wiki). Add a short (one line) description to help us keep track.
