I’ve finally made a decision to get a proper second level domain (instead of co.cc).
The new domain will be “ddscentral” under one of the major TLDs:
no, not ddscentral.com (already registered, but without any IP)
no, not ddscentral.net (not my kind)
so, it will be ddscentral.org.

So, if domain registration goes smoothly, the blog will soon have a new location (and I will have a new email).

I also plan to create a new (second) blog in my native language (not English).
