Reuse the patch from the last campaign and adjust it to use the new campaign parameters and guided tour name.
@Verena please provide the necessary data here
- Guided Tour name: "einfuhrung"
- Campaign #1 name: "wmde2017summer1"
- Campaign #2 name: "wmde2017summer2"
- Campaign #1 link: https://de.wikipedia.org/wiki/Wikipedia:Wikimedia_Deutschland/Entdeckungen-sortieren?campaign=wmde2017summer1&wmdesource=bannerclick
- Campaign #2 link: https://entdecke.wikipedia.de?campaign=wmde2017summer2&wmdesource=bannerclick
The sample code from last time can be seen @ https://gerrit.wikimedia.org/r/#/c/347831/
A fix needs to be put in place to ensure that registered users can not be logged out, see the banner, click the banner, then log in (NOT REGISTER) and then have a chance of seeing the guided tour.
