Today Wikimedia Foundation announced that it has finally added the ability to edit Wikipedia from mobile devices. In that you can able to do so from the desktop.
This is an increasingly important feature, as over 15% of Wikipedia’s users are already accessing the site on mobile devices. This number will obviously continue to trend upwards.
The feature is starting out in trial mode, available only to those with Wikimedia accounts. If this applies to you, to access this edit feature by using the pencil icon. If not, you can easily sign up for an account.
