One final note: The renewal email from Quicksilver.co's hosting was mistakenly routed to my spam folder and I missed the renewal payment for the website. Because of this (as you may have noticed), the website currently has a "suspended" error. Upon noticing this oversight, I immediately paid the outstanding invoice and I expect the notice to be taken down by tomorrow. Sorry for any worries or confusion this may have caused!
http://quicksilver.co/ is still down and dev's last activity was on Last Active: February 22, 2015, 07:14:08 AM .
Another abandoned project?
No, Quicksilver is definitely not abandoned

I did, however, let a typo slip through and wrote "quicksilver.co" instead of "quicksilvercoin.co." If you go to the latter webpage, you can see that it is up and running just fine.
