We completely understand that you may not know what to report on quite yet, but we do find that it is very important to go ahead with reporting on your project. You may consider reporting on any updated planning that has taken place or sharing a story from the field. You could also reflect on any work within your organization that may later impact your project.
By submitting a project report, you are showing any donors and potential supporters that you are still engaged with the project and hopefully encouraging them to donate again!
