I just searched on Google, which sent me to relevant WordPress sites for changing my name and I believe the one that I ended up referring to is: http://en.support.wordpress.com/change-your-username/#change-username . However, I'm not hundred percent sure as it was about a month ago and I should have written it down. I do remember that there was an option next to some boxes that could be checked and the question was basically "do you wish to delete the older blog url?," but I did not check the box and I thought I was safe. However, I was not. It seems that my old url did get deleted and any links previously that used the old url are now invalid. I may not have used the instructions I mentioned previously although they seem familiar to me (perhaps I did so much research after my blunder). I also remember that I just intended to change my username and then I was presented with the option if I wanted a matching blog url. If I hadn't been presented with that option, I don't think this would have happened. Can anything be done to undo it? If not, it's okay as I have begun to try and publicize my posts with links that include just luchanik and not luchaniktravel. However, what happened was very annoying. There should be a way to go back and revert back if you do it within an hour or so of your mistake. There should be a way to contact someone at WordPress by phone, but I had looked all over and could not contact anyone that way when this happened. My only option was the forums.
