WordPress 3.3 introduced a new welcome panel designed to provide a better experience for new users installing WordPress for the first time. The panel would normally be shown to new owners of sites in a network, but this may not be desirable for all networks. This plugin dismisses the panel for new sites and users.
This plugin applies only to multisite, and must be network activated.

Hide Welcome Panel for Multisite

Prevent users from seeing the welcome panel (added in WordPress 3.3) on new sites in a network.

WP Getting Started replaces the WordPress Welcome Panel (the one you see on the Dashboard after a fresh WP installation) with a simple 4 step walkthrough: choose and/or customize your theme, add pages and add posts.
At every page in the walkthrough, users get a short explanation of what they are doing – for example what the difference between a page and a post is. When they have completed a step, they are automatically taken back to the walkthrough on the Dashboard.
WP Getting Started is fully compatible with multisite networks, to give new users an easier introduction to the WordPress admin interface, and is no more intrusive than the original Welcome Panel in WordPress (further explanations only show up when the user follows the links from WP Getting Started).
This plugin is fully compatible with <a href="https://wordpress.org/extend/plugins/live-theme-preview/" rel="ugc">Live Theme Preview</a>, a drop-in replacement for WordPress’ native Themes interface.
This plugin only works with WordPress version 3.4 or later.
This plugin is only freshly released, so use with care. Please leave any comments, bugs or suggestion in the Support section of the plugin page!
