An admin commented here that Tinycards isn't ready to be released online yet
Quote from the comment --->
We've been testing the Tinycards website internally and as some of you saw, it's almost ready! There is still a lot of bug-squashing and polishing to do though, so we appreciate your patience as it'll be just a few more weeks until launch.
Hope this helps!!! :-) - SportsOcean
I've tested it out online last week, it seemed like it was ready because it was perfectly usable and had everything similar to the app. My thought was that it is just down right now. After reading that comment, you've informed me that it was just an accidental release (just like the Hindi for English Speakers forum). Thank you for the information! Have a 'handful' of Lingots.
I was using it last week too and it seemed fine as well! I accidentally stumbled upon that post when I was trying to find out what happened to the page a few days ago (I had already bookmarked Tinycards)!
Thank you so much for the very generous handful of lingots!!!
I believe that Tinycards for Web is temporarily down at the moment. Try again in a few hours or so.
