I have a membership from an organization e.g. ieee.org and I have some options for my email ID which I want to use in academy and professional work. I'm not a native English and I'm not familiar with the culture involved. I have these three options:
(consider my name as Serim Doe, which Serim is my first name and pretty rare, I didn't want make example of John Doe which is very common name).
I personally prefer Serim@ieee.org since it is more concise and shorter, but I want to know if making ID of only the first name is appropriate or not.
