I took a look at jw-media.org to see if I could find any mention of the "faithful and discreet slave" or any mention that Jehovah had chosen the governing body as his sole channel on earth.
Strangely enough, there is no information about the "faithful and discreet slave"
I am wondering if their Frequently Asked Questions page is none other than a "Questions From Readers" page, created by the writing committee.
If you examine the Knowledge Book and the What Does The Bible Teach Book, you will find that the doctrine of the "faithful and discreet slave" is either omitted or not introduced until near the end of the book, when a bible study is already hooked on the idea that Jehovah's Witnesses are the only true christians.
Let's examine some of the information given about who Jehovah's Witnesses are from their website:
http://www.jw-media.org/beliefs/membership.htm
Organization
Following the model of first-century Christianity, Jehovah's Witnesses have no clergy-laity division. All baptized members are ordained ministers and share in the preaching and teaching work. Witnesses are organized into congregations of up to 200 members. Spiritually mature men in each congregation serve as elders. A body of elders supervises each congregation. About 20 congregations form a circuit, and about 10 circuits are grouped into a district. Congregations receive periodic visits from traveling elders. Guidance and instructions are provided by a multinational governing body made up of longtime Witnesses who currently serve at the international offices of Jehovah's Witnesses in Brooklyn, New York.—Acts 15:23-29; 1 Timothy 3:1-7.
For starters, there IS a clergy-laity decision. What the reader is not told here is that ALL appointments of elders are made by the Society, not by the congregation. The congregation elders can only RECOMMEND appointment, it is the Ciruit Overseer who approves it.
While they say there is no clergy-laity division, the truth is that serving as an elder gives that one authority in the congregation, something that would not be present if there were no clergy-laity divison.

The Bible
It is God's infallible, inspired Word, upon which Jehovah's Witnesses base all their beliefs. Some portions of the Bible are to be understood figuratively, or symbolically.—2 Timothy 3:16, 17; Revelation 1:1.
Yes, many religions accept the Bible is the inspired word of God, but what does the Watchtower omit?
"...the Bible is an organizational book and belongs to the Christian congregation as an organization, not to individuals, regardless of how sincerely they may believe that they can interpret the Bible. For this reason the Bible cannot be properly understood without Jehovah's visible organization in mind."

Beliefs—Frequently Asked Questions
Are you Christians?
Yes. We follow Jesus Christ, the Son of God, and put faith in the ransom sacrifice he provided for the salvation of mankind. We imitate his example in preaching and teaching and in our dealings with fellow humans. We also look forward to living in true peace on earth under his heavenly Kingdom.
What do the Watchtower omit in this answer?
"we cannot find the scriptural guidance we need outside the 'faithful and discreet slave' organization.'
so, in other words, you can't follow Jesus without the "faithful and discreet slave"
IMHO, the issue of deliberately omitting and downplaying the doctrine of the "faithful and discreet slave" should be at the top of any agenda to expose the Watchtower Tract and Bible Sociey for what it really is - a fraud.
