I've got a red #1 in my plugins menu title on the left.  There are a slew of plugins installed here(by the previous admin) and all of them say disabled.  Should I just remove these?

 

We do recommend that you uninstall (not just disable) any plugins or apps that are not in active use, unless you have a specific reason to keep some of them.

(Note that you may encounter problems uninstalling one or more of them, depending how out of date they are, but if that's the case you'd need to contact its respective author for assistance in removing it.)

Anything disabled is not being used. If you’re happy with the state of your community, you can remove them.  As a best practice, it might be worthwhile making a full backup of your site before removing them in case you realize later on you needed it. 

A lot of them are pretty outdated. Members Country, for example, is an app for a while now. You can update it for free if you still want to use it.

Thanks!
