Note: Read general policies related to payment for new and existing timelines 
- Timeline of the International Red Cross and Red Crescent Movement (This is and took too long, but still more content can be added)
- Timeline of bicycle sharing systems (Feedback addressed with check marks. Check ):
- Some of the rows that should have a country column filled in have it missing ✔
- Many of the rows can benefit from having the city entered parenthetically, but don't ✔
- The row "A number of researches relative to bicycle-sharing schemes emerges." doesn't feel clear enough (also the grammar/sentence structure feels awkward). ✔
- It may be helpful to add more context for the launch of individual bike-sharing systems, e.g., any distinguishing features, and what generation they are. This is done already for a few rows, but it may be worth looking at others to see if any more context can be added. In particular, when a second bike-sharing system launches in a city that already has one, it may be worth explaining how the systems differ and why a second one was needed. ✔ (more context was added to the rows)
- Divvy in Chicago may deserve a row ✔
- There could probably be more rows on successes/failures of existing bike-sharing systems. ✔ (successes and failures were added in the same rows that indicate the system launches)
- More rows were added

- Timeline of Y Combinator (returned with feedback):
- For timeline of YC it would be good to add timeline rows for the batches where various top YC companies were accepted. List at "
- "For Michael Seibel, also mention him becoming CEO of the Y Combinator core unit" ✔
- The evolution of Y Combinator's request for startups page should be recorded"
- "And didn't yc have startup school for many years, not just in 2017" ✔
- "For Peter Thiel you have a row on him joining YC but not on him leaving it" ✔
