Dear Niel,

Sorry to have caused trouble with the offsets.  
I have no excuse for not having read the help file line about offsets
(moreover, English is my mother-tongue.). I (naively) assumed it was
o.k. to submit a sequence exactly as the text boxes are filled in in the
example from the submissions page.  

That said, I think the following sentence from the submissions page:
http://www.research.att.com/~njas/sequences/Submit.html

What IS the value of the "index" or "subscript" of the initial term?
(For example, if the sequence counts graphs on n nodes with some
property, what is the first value of n?)
box{0}

Should be replaced with something like:
Please enter the values of the "index" or "subscript" of the initial
term as well as the position of the first entry whose absolute value is
greater than or equal to 2 (or 1 if no such entry exists)? Write this as
a, b (do not use parenthesis).

Also note that it seems the word "Offset" given next to the 3rd bullet
under the headline "Formula"
http://www.research.att.com/~njas/sequences/eishelp2.html
is a broken link.

Sincerely,
Creighton
