Just passing by. Completely unrelated.
Try emaling at email@example.com or firstname.lastname@example.org. High quality high priority 1:1 assistance is that what they've promised to you as a paid user and it's kinda suck it they don't even bother to respond. Other users said that Lingvist was very responsive and you are the first telling it's the other way around.
@Nicholas-0 i would be surprised if free version would have specially introduced bugs to make people pay, so it's completely expected that you face the same issues with free and paid version. Are they ignoring your emails, your inquiries through help menu or your messages on forum?
@annika_a there is no fanfare at the end of the course, but there is a greeting message. And you'll never get the badge if you would just wait for it. If you want one, you have to join the group manually and you'll get the badge even if you have 0 learned words. Great motivation indeed.
Regarding Kärt's answer on word count, I guess there was not a lot of options for her, as due to crappy coding and other "peculiarities" that counter is drifting a bit on most of the accounts. It is possible to add even more crappy coding on top of that, but it not the top priority for Lingvist.
@Su-Carey indeed creating a new account is the simplest way, alternatively you can contact Lingivst as described here. Keep in mind that free users are limited to 3000 words. If you are a paying user, you might try contacting Lingvist though 1:1 support from the help menu in your account, that's supposed to be the fastest way.
I agree that motivation should be preferred over self-control and discipline if possible. From my personal experience I tend to believe in ego depletion effect, so I would prefer having fun and gaining the same results over draining the pool of a willpower. Streaks on Duo keep forcing me to maintain at least minimal language-learning activity every day, so I think they work thus are not stupid or useless.
