I'm using POEditor with multiple projects in order to handle multiple resource files in a single application. This works great, but one hiccup I've encountered is that contributors sometimes forget to join all projects. I then either send them a reminder email or they ask me "where are the rest of the strings?"

Not a big deal, but a simple solution that might streamline this would be to allow administrators to assign contributors--possibly limiting it to only those already joined in one or more projects--to other projects within your account.
