Is Udemy the best place for a webinar for game devs, or should I look elsewhere?

Have you considered utilizing a tool like Webinar Jam? You can pre-record your webinars, turn them into evergreen webinars and set the entire system up to provide specific dates and times for the recording, including a, "Your in luck, our next one starts in 15 minutes!" option or something like it. Three weeks is a long time to wait when we are a society that want instant gratification so offering something like this may be a key for more frequency. Also, if you have a way to monitor the open rate of those five reminders, I'd encourage you to look at that statistic. Even though your current schedule is three weeks out, five reminders seem a little high and I'm thinking you'll see that the two out of the five e-mails don't even get looked at. Other suggestions would be to look closely at your webinar title, the length of the webinar and even the hook you are pitching to encourage people to watch. You want to give off a high perceived value to entice registration and attendance.

I am an entrepreneur without a single degree or certification to my name. I'm certainly not anti-education (in fact, I've taught some university classes), but higher education wasn't the path I chose. My question for you is: what type of learner are you? I learn best when I'm self-directed, studying things that fascinate me, and able to either apply or teach what I'm learning (in fact, I think teaching is one of the best ways to learn). So, I've taken ownership of my "education", and I am constantly learning. I read books and articles, listen to podcasts and other audio programs, attend conferences and events, and seek mentors and peer-learning environments. It has worked well for me, but not everyone is built that way. Some people learn better when the education is structured for them, or when they have schedules, deadlines, and feedback (i.e. grades) on their learning. Even for structured learning, college / university is not the only option. There are incubator / accelerator programs, entrepreneur boot camps, mentoring groups such as SCORE - some of it depends on where you are located, or whether you're willing to travel. The bottom line is that education is not optional (especially for an entrepreneur), but there are several ways to get an education. You need to figure out what kind of learner you are to determine what path (or combination of paths) you should take.

As far as targeting a single high school, I don't know. But, in terms of platforms this audience uses, Tumbler, Instagram, Snap Chat & Vine would be good targets.

There are many discussions these days about how small business owners struggle to get connected and stay connected with their communities of interest. Whether the priorities are personal or professional, the concerns are the same; where do I go to find and share amongst my peers, relevant and consistent exchanges of ideas, values, interests and market intelligence? Building and maintaining an online community centered on your agenda is the single best way to find what you’re looking for. My thoughts continue at http://mvb.me/s/35d923

If you're bootstrapping, pay yourself less and re-invest in the company. If you've raised money, then pay yourself average salary as you aren't subsidizing and getting more stock (for the $$) as an investor would - so once you raised, then it's a shared risk - don't make the financial subsidy a thing you take on. I see this happen so many times where venture funded founders pay themselves little (ex: $40K / year) to look good, but the truth is you should be making $75K and instead you don't have the financial resources to a) pay off personal debt, b) hire help to be able to have more time to work, c) enjoy life with your partner/family and in turn burn those relationships. Don't make that mistake if you have financial partners as investors. Be fair, but don't take a financial loss every month to save face.
