I often allow players to see other player's character sheets in my games. It helps to allow players to help other players create or level up their characters, and/or discuss tactical options or how power work, or to recommend powers, etc. It's also useful when a player misses a session, I'll allow the players who made it play the character in battle, or use the player's skills (Like, say, have a rogue unlock a door). Sure, we all wish the Rogue-Player could make it to game, and it sucks not having their input on things, but it sucks even more when you're trapped in a dungeon and can't access their skills. I've dealt with players missing session various ways throughout the years, one way is to allow players to access the skills. I've got enough NPCs to handle. And, I've had it happen in games where players either by accident or on purpose have messed up another player's sheet in roll20, because the only way to allow players to see the stats is to also allow them to change them. I've resorted to keeping copies of the character sheets, but as Roll20 doesn't make it easy to copy character sheets, and it's easy to let note taking and character sheet copy-upkeep go by the wayside, keeping a second version of a character sheet can be a real pain. So, yes, please allow us to give access to seeing another player's character sheet without actually being able to edit it.
