To whom it may concern,
Especially, Opera Coast developing team,

I did input http://www.短歌新潮.jp/.
However, Opera Coast opened http://短歌新潮.jp/.

www.短歌新潮.jp and 短歌新潮.jp have different IP
addresses, i.e., different servers and contents.

Please DO NOT SUPPRESS "www." automatically.

Dig DNS A or AAAA records and if IP addresses are
different, distinguish these web servers.

And Safari can open "https://www.短歌新潮.jp/" but
Opera Coast cannot. Awesome surprised!!

Yours,
Ken

P.S.
Why Opera Software has support@opera.com, NOT?
I want direct supports, not forums.
