Improve experience when inviting users to a project on gitlab.com

When I try to subscribe new user to my project (developer or else), I must remember full name or email of this. When someone has some short or fake name (devel0p3r) , or I don't remember email - I must open another project where that person is assign and check/copy name or else...

Could You add feature that's suggests in first order users that I have in some relations (exists in my others projects, or I have access to theirs projects) ?
