I’m an incoming grad student at a US university and I’ve been asked to set up my email alias. The university doesn’t have an explicit policy on what the aliases should look like, but I’ve noticed most faculty and grad students have gone with either of the following:

> 
> firstname.lastname@acme.edu  
> 
>  lastname@acme.edu
> 
> 
> 

However, my first name is shorter, available, and easier to spell.
It’s an unusual name in the US (which helped me secure firstname.com), but it’s four characters and hard to get wrong.
Therefore, I’m thinking of going with:

> 
> firstname@acme.edu
> 
> 
> 

**Could that be interpreted as inappropriate/unprofessional/overly casual by some, or would it be fine?** It’s one of the top-five programs in economics in the US – everyone seemed friendly on my fly-out and they’re probably among the less formal departments I’ve visited.
