-For changes in the interface, it can be helpful to create a mockup first.
+For changes in the interface, it is helpful to include a mockup. Issues that add to, or change, the interface should 
+be given the ~"UX" label. This will allow the UX team to provide input and guidance. You may 
+need to ask one of the [core team] members to add the label, if you do not have permissions to do it by yourself.

 If you want to create something yourself, consider opening an issue first to
 discuss whether it is interesting to include this in GitLab.

+### Security Concerns
+
+**WARNING:** Be careful when choosing the domain used for receiving incoming
+email.
+
+For the sake of example, suppose your top-level company domain is `hooli.com`.
+All employees in your company have an email address at that domain via Google
+Apps, and your company's private Slack instance requires a valid `@hooli.com`
+email address in order to sign up.
+
+If you also host a public-facing GitLab instance at `hooli.com` and set your
+incoming email domain to `hooli.com`, an attacker could abuse the "Create new
+issue by email" feature by using a project's unique address as the email when
+signing up for Slack, which would send a confirmation email, which would create
+a new issue on the project owned by the attacker, allowing them to click the
+confirmation link and validate their account on your company's private Slack
+instance.
+
+We recommend receiving incoming email on a subdomain, such as
+`incoming.hooli.com`, and ensuring that you do not employ any services that
+authenticate solely based on access to an email domain such as `*.hooli.com.`
+Alternatively, use a dedicated domain for GitLab email communications such as
+`hooli-gitlab.com`.
+
+See GitLab issue [#30366](https://gitlab.com/gitlab-org/gitlab-ce/issues/30366)

+### Setting up NGINX Ingress for Prometheus monitoring
 
 Version 0.9.0 and above of [NGINX ingress](https://github.com/kubernetes/ingress/tree/master/controllers/nginx) have built-in support for exporting Prometheus metrics. To enable, a ConfigMap setting must be passed: `enable-vts-status: "true"`. Once enabled, a Prometheus metrics endpoint will start running on port 10254.
 
-With metric data now available, Prometheus needs to be configured to collect it. The easiest way to do this is to leverage Prometheus' [built-in Kubernetes service discovery](https://prometheus.io/docs/operating/configuration/#kubernetes_sd_config), which automatically detects a variety of Kubernetes components and makes them available for monitoring. NGINX ingress metrics are exposed per pod, a sample scrape configuration [is available](https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml#L248). This configuration will detect pods and enable collection of metrics **only if** they have been specifically annotated for monitoring.
+With metric data now available, Prometheus needs to be configured to collect it.

Since NGINX ingress metrics are exposed per pod, a scrape job for Kubernetes pods is required. A sample pod scraping configuration [is available](https://github.com/prometheus/prometheus/blob/master/documentation/examples/prometheus-kubernetes.yml#L248). This configuration will detect pods and enable collection of metrics **only if** they have been specifically annotated for monitoring.
 
 Depending on how NGINX ingress was deployed, typically a DaemonSet or Deployment, edit the corresponding YML spec. Two new annotations need to be added:
-* `prometheus.io/port: "true"`
+* `prometheus.io/scrape: "true"`
 * `prometheus.io/port: "10254"`
 
 Prometheus should now be collecting NGINX ingress metrics. To validate view the Prometheus Targets, available under `Status > Targets` on the Prometheus dashboard. New entries for NGINX should be listed in the kubernetes pod monitoring job, `kubernetes-pods`.
