[seqfan] Re: Additional keywords for OEIS

[Frank Adams-Watters]

I don't know what you mean by categories. Is there a reference to this 
in the Wiki?

I like the idea of new keywords, and I like the idea of categories.
Categories seem like a great solution to many problems because they 
would
be (by design) extendable. Unfortunately I haven't had time to look 
though
this part of Russ' code, but I intend to work on this eventually.
