How to invite people to your project?

If you go to their profile page, there is an "Invite to team" option in the sidebar; this will allow you to add them to whichever mod(s) you like.

I still need to add a member search function, but you can get to their profile by changing the url on your account page and appending /[username] - for me, https://edge.hoi4modding.com/user/jordsta95 or by mentioning them in the forums, e.g. @jordsta95

Thanks
