If we could keep the chat here to English that would be appreciated.
@Electrik- If you think there should be more explicit statements about whether an asset is editable or not then that's valid criticism and we, admin, will take it on board, but that is a conversation to have with staff/admin - Not the author.
Pursuing this debate here in this way is not productive.
The author's license and description didn't explicitly state that modification rights were granted, and that's their choice.
If you don't like that then that's OK, and you've made that point,
and if you think Codefling should enforce clearer descriptions/terms then that's OK too and, as said, that's a discussion to have with staff.
Either way, this is probably a good time to end discussions with the author.
