FAQ is ready, but disorganized

Seqfans:

    As a compulsive organizer, I think we should categorize the
    questions, like below.

    I have a rarely-asked question. Some sequences have attachments
    stored in the OEIS itself; should that be encouraged? (Yes, at least
    some of the time; but how much bulk can OEIS handle?)

----- Use -----

What is the purpose of the OEIS?
How do I cite the OEIS in a paper?
Can you give some examples of successful applications of the OEIS?

----- Searching -----

How many terms do I need to look up a sequence?
How do I find which sequences cross-reference a particular sequence?
I looked up a really basic sequence (the number of abelian groups of order n, in fact), and I was surprised to find that it wasn't there. How come?
I've heard about the Motzkin numbers, but I don't know the beginning of the sequence, so how can I find them?
I was trying to find the entry for the Fibonacci numbers, but when I entered 2, 3, 5, 8, 13 I got too many matching sequences.

----- Semantics -----

Sometimes a sequence will say "n^2 + 1 is prime", sometimes it says "Primes of the form n^2 + 1". What's the difference?
Where can I find an explanation of all the different keywords, like "core" and "nice"?
What does the "offset" mean?
What does the keyword "base" mean?
Can you give an example of a "dumb" sequence?

----- Submissions -----

Which sequences should I submit to the OEIS?
If I just make up a definition of a sequence, should I submit it?
What *** should I do before submitting a new sequence?
How long should I spend on a submission to the OEIS?
What "Subject" line should I use when submitting a new sequence or comment?
*** What kinds of number may appear in a sequence?
What are some of the reasons why sequences are rejected?

----- Notation -----

What notation should I use in equations in the comment and formula lines?
Is it OK to use LaTex notation in equations?
Should I use juxtaposition to denote multiplication, or should I put a "*" or "." between the things being multiplied?
How should I indicate summations?
Should I denote infinity by "oo"?

----- Format -----

Where can I find an explanation of the internal format used in the database? The %I, %S, etc. lines?
I notice that sometimes you give more than three lines of terms for a sequence. What's the story?
What's the preferred way to enumerate array elements to get an OEIS sequence?
How should an array or triangle be included with the submission?

----- Participation -----

How many new sequences and comments come in each day? How big is the database?
What can I do to help?
Can one subscribe to the comment mail queue?
