I'd like to register the artist of this picture in the database (also of explicit post #159159), but the most suitable handle -kabocha- is already in use. Is using 'kabocha_2' recommended, or what?

If a senpai can give me an advice...

I'd go with his email address, ie. pumpkipumpkin. Not overly convenient to type, but with a "pumpump" alias it should be manageable.

Roger that. Thanks

Artist renamed to dotekabocha.
