You can start PMing me with that. Just keep in mind that I may need up to 3 days to answer to every request ;-)
open beta in some minutes. Since there is nothing "perfect" right now and eXocoin will not be "just a program" (it must deal with a virtual currency properly and without serious security issues) we definatly will go for a 2nd open beta before the launch with the (nearly) final product then. You can then try to attack the software with whatever you like. As for this beta you are maybe able to crash the system. If that will be the case we will investigate and restart after a fix - providing an update as well then as auto-update.
