[seqfan] Re: Websites on OEIS server

[Neil Sloane]

Dear Sven, nice work!
Are we talking about just one html file?  If so, you can upload it yourself
(assuming it is under 10 megs).

Go to the sequence, click Edit, click 'I want to attach a file", upload the
file,
edit the author and title, put the links in alphabetical order, click Save,
click These changes are ready ...

If you send me an email when you've done it, I can take a look and make
sure it worked.

Or, of course, if you run into a problem, email me the html file and I will
do it.

On the other hand, if this is a tree of html files, - with many subpages, -
better send me the zip  file

And thank you for doing this.


Best regards
Neil
