Forgot to add – the other reason folks mentioned using the Web Client screen was for admin features that were only available in the MUSH client.
2.0 adds a bunch of those to the web portal, like admins being able to reset a player’s password. Other than building, which IMHO is best done through a proper MU client anyway, there shouldn’t be anything that can only be done in client.
If there is, just let me know because it’s probably just an oversight.
