There are many different plugins and themes that are currently used in wordpress for web.unc.edu sites, but if you want to add another, then there are some guidelines that should be followed first.
First, you need to make sure the new plugins can work on web.unc.edu, and in a wordpress multi-site environment. They should not have excessive use on processes since it is a shared service among all sites. Flash based plugins are not allowed because they put a strain on the server.
Second, you need to make sure it has large use potential. Not all requested plugins are added to web.unc.edu because every plugin added to the service, even when not activated, increases the amount of time it takes to load websites. Therefore, only plugins that have the potential to be used by many sites will we consider to be added.
Last, you need to check if the plugins already exist in some form on web.unc.edu. For the same reasons that were previously stated, adding multiple plugins that do the same thing is not suggested in order to avoid a long load time for sites. So look for existing plugins to accomplish what you need.
If the plugin you’re requesting fits these requirements and guidelines, then please post on the web.unc.edu support forum under ideas so we can gather some more input about it from other administrators.
