Plugins
Isn’t this nice: A free plugin!
Pro Sites & Gravity Forms integration
Found here, this plugin is your little friend when it comes to automating and customizing your MultiSite network. Used on the Host Mijn Pagina network, I decided to deliver it for free on WPMUdev’s forums.
This plugin simply integrates the input from Gravity Forms to Pro Sites, it’s a one-way process so it’s very secure too!
From there Pro Sites takes over and handles everything, like the use of plugins, ads, themes, storage, etc.!
Auto Description
Auto Description is also posted on the WPMUdev’s community page for free, and I will consider posting this on the WordPress.org domain.
Originally written for the LightSpring theme used on Host Mijn Pagina, this plugin automatically adds a few things as meta tags into the header of your HTML document, this means that search engines and Facebook will easily read your website’s data.
Although it’s a heavy plugin, because it’s reading your page’s contents, it’s very well written I must say :). I’m a speed freak when it comes to page loading times, and this plugin reflects that.
AutoDescription is a plugin when you don’t want to think about SEO things and just get it over with.
Pro Sites Extras
Got users on your WordPress MultiSite? Are you using premium content?
Then why do you allow them to delete their website? Or worse, let them export their site using up all your system’s resources?
Fear no more: Pro Sites Extras will selectively adjust these menus for you.
Pro Mime Types
Want more freedom of choice when it comes to uploading files in your MultiSite network? Are you still using or want to use premium content?
Look no further, I made a nice plugin for you! Now you can allow everything (or nothing! D:) with Pro Mime Types!
Oh… and it has Pro Sites support :D
W3TC Auto Pilot
A must have for MultiSite owners: No more clearing cache, no more explaining to your customers why their pages, themes, widgets, etc. don’t change when they are edited. This plugin hooks into your W3 Total Cache configuration and your website to create an automatic experience. Like your WordPress is on Auto Pilot :D
Get W3TC Auto Pilot and your problems are gone :)
