Feature: Ask community for feedback/review
As a user of the GitLab community I'd like to tell other community members that I'm interested in getting feedback for code that I wrote. I'd also like to review code of others project in my favourite language (as long as they are interested).
## Rationale:
Code-review is probably the best way to improve coding skills (being reviewed as well as being the reviewer). In my experience discussing about class design, etc. is *not* on the agenda of many projects. So as a potential reviewer it's hard to find projects that appreciate feedback. And for project owners it's hard to find (experienced) reviewers that are interested in discussing the design of your code.
I think that a feature like `Open review request` will
* improve code of many projects
* increase collaboration
* help people drawing attention to active projects
* and thus strengthen the GitLab Community
