It would be nice to have a short glossary on hover for words that we use on the committee that might not be clear to outsiders.

Here are a couple that we have gathered so far:
Delegate - A person who represents an ECMA International member organization
Member - An organization that has joined ECMA
Champion - A person who presents and supports a proposal through the tc39 process
Contributor - A person who is working towards making a proposal a reality
Proposal - a proposed new language feature that has not yet been added to the language
Ecma international- A standardization body that takes care of the ECMAScript spec
TC39 - Technical Committee 39, a committee organized by Ecma international
ECMA-262 - the official name of the ECMAScript specification
ECMA-402 - the official name of the internationalization specification

Any other suggestions?
