User blog:Gulfstream/new user looking for the right way to delete wrong named wiki to start working hard...

Please help me to delete one created wiki. I tryed to convert the language, but seems i met unexpexted issue. I've changed my strategy and instead making few wikies on different languagaes i'll work on one wiki with pages in different languages, so the wiki with the bulgarian language navigation settings must be deleted to avoid wrong search resoults for the viewers and users. The general search tracks the name to the old wiki, which i want to delete. The old wiki, which i want to delete has new native alternative name and native language navigation, but the main name in english is still active, so it's useless. I want to delete that wiki to start work properly on the same named wiki. If i can't explain properly the issue the wiki, which i want to delete is 'GULFipedia' with the bulgarian navigation settings:

ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ

I want to keep working on the wiki with the same english name with english navigation settings.
