Plugin Installation Question

[usuallymatt]

I'm new to Roundcube. I'm using ISPConfig. I setup a new site and DB and have it all working perfectly with my mail server. I can login, send mail, store contacts, it's all good.
I wanted to try a Calendar plugin so I downloaded it and dropped it into the plugins folder. Apparently I should see a calendar button.
Are you able to install plugins simply by dropping the plugin folder into the plugins folder in your site?
If so can anyone recommend a good Calendar plugin that works.
Also, is Plugin Manager compatiable with 0.9.5?

Thanks,

Which calendar plugin are you using? If your using the Kolab calendar you just need to follow the plugin guide: http://trac.roundcube.net/wiki/Doc_Plugins

Thanks. I'll give that a go.
