I have an idea for a project but my time is limited. And I would also like to get the opinions of others before even starting the project. How should I go about recruiting members to this project?
Describing your project would be a nice first step.
Or you can create a repository, then create issues where you explain your ideas and then here you can start a new topic on Project Development Help and Advice to get help or collaborators.
Tagging an issue with “Help Wanted” is a way to attract attention. As Wabri mentioned, creating a repository and writing some issues are the first steps.
