Here at MyWikis, we are all about customizing your wiki! A major part of that is MediaWiki extensions and skins. We're able to install most MediaWiki extensions and skins (to a reasonable extent).
As extensions are created by third parties, the ability for us to install an extension on a wiki depends on whether the extension is up to date or not with your wiki's version. To see your wiki's version, the software powering it, and the extensions currently installed on your wiki, please visit your wiki's Special:Version page. Certain extensions are not supported on our MyWikis Basics, Pro, or Corporate plans, but may be available through our VPS plans. In the rare case that an extension needs to be purchased, MyWikis will wait until the customer purchases the extension to install it. Contact support for more information on whether we support an extension or not.
To install an extension or skin onto your wiki, please create a support ticket and specify the extension or skin you would like installed onto your wiki. A link to your extension or skin would be very helpful.
We are usually able to fulfill your requests. In the rare case we're unable to install an extension, we'll let you know why. Additionally, we can install up to 10 extensions for your wikis each month.
