This domain used to reside on the aplus.co.yu domain. .yu domain belonged to former Yugoslavia, which has died, despite the futile attempts to keep whatever is left of it under the same name.
With it, the TLD is on its way out and the new Serbian domain is .rs
Thus this blog and all its auxiliary content is now under aplus.rs web address. All the links pointing to old web site will get R=301 message and will hopefully soon be pointing to new addresses.
