it's a massive endeavor, and it will take ages to complete, but...
going forward (especially after the new year), everything will be organized similar to that directly from the site, so you can access the stuff with the My Feed feature.
seasons will be clearly marked as 25 lessons and grouped as such. within seasons, if the lesson appears in a series, there will also be a way to organize by that. so
level, season: Lower Intermediate Season 3
series: How to Meet People Online
title: How to Meet People Online 1
level, season: Beginner Season 4
series: Nihongo Dojo: Meet the Parents
title: An Opportunity Arises.
in the beginning we didn't have a definition of what a season actually was. but now we've got one and hopefully can start organizing things better right from the start, so you don't have to do too much work yourself.
but it'll take time. so this is just a spoiler. hehheheeh
