If you are the kind of person that likes to study together with a friend or in a group, let me present you some ways to connect to fellow challengers. If you haven't heard of any of these platform's names before, keep on reading to learn what they are about and how they might benefit your challenge experience. The three platforms below are those I use frequently myself (both for language learning purposes and private stuff) and can therefore recommend them whole-heartedly.
Probably my favourite way to connect to people, since it gives you the opportunity to both talk and chat with others. That is, if you want to. You won't need a mic or a headphone if you are interested in texting only. Also, conversations with a bigger group of people still feel structured and easy to follow.
I set up different types of channels for you to switch between and thanks to the wonderful suggestions from the last Language Jam, there will now be off-topic and general language channels, too. You can use Discord basically on every device: You can download it for Windows, Mac, Linux, Android and iOS, or just use it in your browser.
Known to most, this platform might appeal to all those of you, who like posting pictures and short videos. The text limitation under a picture is much more generous in comparison to Twitter, and a comment and direct message function allow you to chat with other people either publicly or privately.
The easiest way to connect to challengers with the same language would probably be by using hashtags like #LangJam[+ challenge language], for example: #LangJamJapanese or #LangJamScottishGaelic. (#LanguageJam works as well, of course.)
You can also make a private group with other challengers who got the same language.
Having a text limitation of 280 characters might sound restricting at first, but will ultimately result in an overseeable stream of messages. Similar to Instagram, the best way to connect with other challengers is by using hashtags like #LangJamAfrikaans or #LanguageJamAfrikaans.
You can send direct messages to other users as well as making group chats to interact with more than one person at the same time.
