It kind of depends on the players. You can set your character sheets to be publicly visible if you'd like.
On your "Characters" menu, if you click the little library book, it
should still make it a publicly visible sheet, but that is then open to everyone on the site to see if they choose to navigate there (for example, going to the game details page of this game and clicking on the character name).
You can check to see if it worked by seeing if you can see this character of mine:
Brainmush
Vs this character that isn't in the library:
Deathwake
That said, if each player would like to give a short OOC synopsis of what kinds of skills and character info you would have shared on the few hours walk so far, that could go a long way towards helping others understand who all is at the table.
