User name change?

[Ship's Cat]

My first user name was 'Shipimages', because that was the name of my old website before the host went bust and I gave up the domain name, and then - after this forum did an upgrade everyone's real names appeared - I reverted to using my given name.

However, I really dislike my given name and would like to go back to using an alias. I know it's possible to change one's user name in the profile settings but I am not sure if it's really the done thing! Would it be ok to change it again? I don't want to change it and get a PM asking who the heck I am. 

Thanks

Or I could put my old name in my sig for a while.

Thanks Ken

Ok, 'Ship's Cat', as I love ships and cats.
