Use my talk page. This is the easiest, yet the quickest method to contact me. Please use this method for templates or talkback messages.
Email me via Wikipedia's email system. This is a good method if you want to contact me privately about something. However, if you are going to contact me about something not so important, I suggest you to not use this method, as it annoys me if you do it too many times.
Email me directly. If you cannot access Wikipedia's email system (i.e. getting hardblocked or banned) Please contact me here: ericcolland@outlook.com. Make sure to:
State that this is from Wikipedia
State your username
Verify that you are the username you entered above (i.e. creating a subpage).

Contact me on Skype. I chat as salty_nuts_ftw, ask an invitation there.
