The problem

I seem to have ended up one of my modules, Archive-SimpleZip, appearing twice in modules.perl6.org.

I suspect that this is because, until recently, I had the module registered via the p6c (using the instructions in Upload your module to p6c . I've subsequently uploaded the module to CPAN (Upload your module to CPAN).

Suggestions

Assuming that this issue is caused by a dual registration, I think there needs to be some documentation on how to get rid of the duplicate entry.
