Well, let's continue brainstorming for possible improvements now; once we 
have the wiki we can start copying across ideas to there and developing 
them further.

Or view/download as a decimal constant, or as a table - or in a different 
base for those "base" sequences not related to base 10 where the numbers 
are entered in base 10.  (As sequences of *integers* not *digit strings*, 
entering the integers in base 10 is the mathematically correct way of 
storing sequences related to any base - but not the most convenient for 
spotting patterns.  Some sequences are present in both the mathematically 
proper base 10 form, and in the own-base form.)

Yes, there are some sequences for which it should really be a matter of 
entering the range you'd like to download as a b-file, rather than just 
storing some initial segment precomputed (though the initial precomputed 
segment will still be needed for searches).

Groups of sequences that are identical apart from their initial terms and 
offsets should really only need one b-file between them (extending one 
should extend all).

When you do this for editors/contributors it also helps address the email 
address problem - you have a profile for each contributor with a real 
name, an email address or web page for contact purposes (possibly with a 
CAPTCHA or registration required to get the email address if there are 
spam issues) and maybe other information the contributor wants to add, and 
just one place to change if the details change or someone no longer wants 
an email address listed directly.
