NSF continues to update Research.gov and, as more FastLane capabilities are migrated to Research.gov, the system will expand until it eventually replaces FastLane for proposal preparation and submission.
Research.gov’s June release now allows preparation and submission of full, research collaborative proposals with subawards. Future enhancements to the Research.gov will allow preparation and submission of separately submitted collaborative proposals from multiple organizations.
While proposers can still use FastLane, NSF encourages proposal preparation and submission using Research.gov. As NSF continues to enhance the new system incrementally, your feedback is being incorporated.
Give it a try and let NSF know about your experience: Research.gov Feedback
