Do you plan to add more crypto for playing the game? Currently, I can only see bitcoin is accepted. Althought bitcoin is popular and is related to your satoshidice name, I think adding more coins would be better to give us more options.
This site is still on its beginning phase, still many things that can be added or upgraded. Give them some more time in order to give what user's want to see on the site. I'm pretty sure they have many homeworks and plans on what to do. They must have their priorities on which ones that should be done earlier and which ones later. Of course, they are open for any suggestions and feedback.
Exactly, the domain is the least on the agenda, it cost money to do that and I'm quite sure after all the testing (paying participants to test the game), organization of promotions (signature and other platforms promotions) the site must be running out of fund. The expenses are quite more then they must have budgeted especially after the had some setbacks in regards to the site not working as well as the expected before the first launched. The development and upgrades wasn't free, that also cost money.
In due time, probably after some profit has been made, other development will come into the picture which one of them is getting a proper domain name that won't put them at danger of any copyright issues.
