I use only free servers and after creating my website I decided to make access to that domain by simple domain name . I decided to use domain alias notlong service
The second advantage of using alias here was to be independant from my file host which I will have to change.
I haven't found a better alias service like notlong, because notlong is easy to remember.
After that I encounter many problems:
* most of forums or social services treat notlong address as a spam,
* Bing so far haven't accepted the notlong domain and others.
Is it another way to have good free domain name? How about the situation when your hosting server will inform you to expire? Only a lasting layer of domain aliases make you independent from the real file hosts.
