I have few more suggestions:
You may delete this post and if agree add to main wiki.
Every contributor should add Github username next to their name & also if service provider: Name of the company. Ex- Mohd - mdwala - Alex Co. (This will generate little attention to user that which service provider helped him, and his activity with core. Same way it will help service provide to gain interest in user). Not sure if can add it with username intead of name.
On Service provider page - Every Service Provider must provide their discuss user-name along with their name. Optional Github username too. (Will help users indentify good developer and this is only way to do this)
