I finished my undergrad last year and have since been working in the private sector.  I'm about to submit a paper with my senior thesis results.  Two questions about corresponding author information:

1. I'm listing my current (private sector) affiliation for various reasons.  We are moving offices, and our address will be changing in about 3 months.  **Should I use the new mailing address or the old mailing address?**  I know it's kind of silly since nobody sends mail anymore, but I'm curious either way.

2. I will probably be going to grad school in a couple of years, and my private sector e-mail will *not* be accessible if I leave.  **Would it be passé for me to list my @gmail.com address for correspondence to ensure I'm always reachable?**

Thanks!
