Should I Install All the PublishPress Add-ons?
No, you don’t need to install all the PublishPress add-ons.
The add-ons will not slow down your site, but we find it very hard to imagine a site that needs them all.
The idea is you only install the ones you need. The same is true of all WordPress plugins.
We recommend you take the same approach with PublishPress. Only install an add-on if you need the features it provides. If you’re unsure if you need a particular add-on, you’re welcome to contact us.
