+# Reminder for Call for Proposals, Tickets, and Opportunity Grants
+
+We hope you are looking forward to our Berlin conference as much as we are!
+
+Today is mostly a reminder that we're accepting Talk Proposals until **{{ cfp.ends }}**.
+
+Opportunity Grants are still open as well. And of course, tickets are on sale!
+
+## Submit your talk by {{ cfp.ends }}
+
+You still have just under three weeks to submit your talk to the conference. Check out the [Call for Proposals page](https://www.writethedocs.org/conf/{{shortcode}}/{{year}}/cfp) for more details about what would make a great talk.
+
+If you already have an idea but are having a difficult time getting your proposal together, you can always ask for talk feedback on the [Write the Docs Slack](https://www.writethedocs.org/slack/). The community is here to help!
+
+- Talk proposals are due by {{ cfp.ends }}.
+- Everyone who submits will receive a response by {{ cfp.notification }}.
+
+## Buy your ticket for the conference
+
+The {{ name }} conference is {{ date.short }}. If you're excited to join us, go ahead and buy your ticket today! The [Tickets page](https://www.writethedocs.org/conf/{{shortcode}}/{{year}}/tickets/) has all the information about pricing and what is included.
+
+This in-person event does have a limited capacity, so do not wait until the last moment to get your ticket,
+as we may sell out some time before the conference.
+
+Similar to our past conferences, we'll have great programming and social activities, including:
+
+- Speaker Presentations
+- Unconference Sessions
+- Sponsor Expo
+- Monday Night Social
+- Lightning Talks
+
+### Opportunity Grants are still open
+
+Interested in attending but need extra financial support?
+We strive to provide an accessible conference for folks of all backgrounds to join. Our opportunity grant application is open until **{{ grants.ends }}**.
+
+View our [Opportunity Grants page](https://www.writethedocs.org/conf/{{shortcode}}/{{year}}/opportunity-grants/) for information and the grant application.
+
