After finishing the MVP for EDHmeetup I decided to share the idea directly with the community I was targetting. I shared the site on the r/EDH subreddit.
The post got a decent amount of upvotes and a ton of great feedback. The first thing I did based on feedback was add international support.
Originally the site supported only the US but after reading the comments on reddit I saw that there was a good amount of demand in the rest of the world.
I probably lost some users by not having international support from the start but hopefully they can find the site again.
