Alternatively, what we can do is that we can ask yerfry, or Hugo to contact Sweet and Sour. There should be an effective non-client communication system - like either working mail, forums, or a section where you can mail staff or Events.

So far, the only effective way of non-client communcation is via Habbi Wiki - one of the most respected fansites in Habbi. But not everyone knows about it.
