You can easily upload your dan invoice to namebios to get the sale recorded.
I tried it with my last sale and all I did was specify the domain and upload the sale invoice.
When it asked me for where it sold I did specify MapleDots.ca via Dan.com to make sure MapleDots got a mention.
I don't traditionally report but I have been experimenting with Dan and Namebios as of late to see if they are a good fit for me.
The problem I have reporting to namebios is I cannot report my hidden domains because they are in specific niche groups where I don't want copycats. Regular 4 letter and misc domains are no problems and I can easily report them.
