I would strongly consider upgrading your domain name to EVForum.com which would be the category killer to give your forum the edge in competing.
SpeakEV forum software is crap compared to Discourse so you have a major advantage there and their brand is terrible.
Your brand, your forum software, and the fact you are the original EV forum will catapult you ahead, which you need to make a point of, but you really need to think about upgrading your brand to EVForum.com or ECForum.com which would especially help expand your reach and attract more signups and quality content.
