As a **user**,
**I want** to inform myself about wikimedia,
**so that** I can apply for a membership on a well informed basis.
Acceptance Criteria:
* In wider viewports, there is a link right of the list of "incentives", leading to [our public website](https://wikimedia.de/wiki/Mitgliedschaft).
* In narrow viewports, the link is displayed below that list.
* The link opens in a new browser tab.
The design team proposed the display of the link as follows:
{F15409996}
Background: We know that quite a few people click on the link for further information about memberships that we offer on the right side of [[ https://spenden.wikimedia.de/apply-for-membership?skin=10h16&type=sustaining&piwik_campaign=thankyou-ba-180101&piwik_kwd=org-thankyou-dskt-180101-ctrl | 10h16 ]].
{F14521536}
Users get redirected to https://wikimedia.de/wiki/Mitgliedschaft after clicking and some of them return to our membership by clicking on the provided link.
On [cat17](https://spenden.wikimedia.de/apply-for-membership?skin=cat17) this link is missing.
Due to the donation receipt mailing which will be delivered around Mar 12th, we need a quick fix of this problem.
