!!Con has subpages for past events: http://bangbangcon.com/2018/

We could do that, too, but from what I could tell it would require adjusting a lot of links to either point to the absolute path "/2018/...", or to make them relative.

An easier option could be to make a copy of this repository, call it "2018.enthusiasticon.de", and create a matching DNS entry. That way, all content could stay the way it is, and we could set up the 2019 version in this repo. What do you think?

I like the easier option personally though no idea how to edit the DNS entries.

I like both options, but the latter definitely seems like less work, which makes it more appealing to me as well!
