 If you dont have a SSL cert yet, there are three ways to get one: buy one, get a free one (eg. via StartSSL) or create your own (not recommended). [You can find more information about setting up SSL and why it's a bad idea to use self-signed SSL here.](help/SSL) 
 
 Be aware that a browser warning about security issues is something that can make new users feel insecure about the whole friendica project. 
-Because of this, Friendica Red will only accept SSL certs signed by a recognized CA and doesn't connect to servers without these kind of SSL. Despite of the negative aspects of SSL, this is a necessary solution until there is an established alternative for this technique.

 **Can I configure multiple domains with the same code instance?**
 
-You can do that. What you can't do is point two different domains at the same database. As long as .htconfig.php exists to keep it from trying to do an install, you can keep the real config in include/$hostname/.htconfig.php All of the cache and lock stuff can be configured per instance.
