I use http://www.centminmod.com/ to configure and setup our servers on DigitalOcean. I'd like to get started with at least one of my forums on SSL. First question is, is there a good guide to walk me through setting this up using nginx (specifically the methods that centminmod uses to install it). Second, anything I need to know about xenForo, other than to start making use of the image proxy system? How to make the change without hiccups. etc Third, what is my best options for SSL certifications for multiple forums. We have at least 4 if not 5 that we could roll this out on if everything goes smoothly setting up the first one. I want something that isn't going to break the bank. This isn't something we need but something that I would like to do and at least start planning for down the road.
