This question already has an answer here:
I use a nickname that makes me identifiable anywhere on the internet. As neither Stack Overflow, nor most of the SE sites are related to my "internet persona", I decided not to register with that name here, but kept my full name instead.
My e-mail address, however reflects to this nickname. To be precise, it is (something like)
firstname.lastname@example.org, and I use it practically everywhere, even for receiving messages from the university.
Now, however, I have to apply to a job to gain experience (I can't have a degree without it) and I was asked for sending a CV via e-mail.
Would it ruin the image about me, if I use
katamori123 as usual? Is it recommended to make an e-mail like
email@example.com or it's safe to keep using the other one?
