Why Sololearn makes me to invite friends

Question

I thought that a word 'solo' means that doing something alone.

Answer 1

Yes, SoloLearn means to learn on your own, yet, when you have a problem you may feel more comfortable to share and tell with those you knew already, your close friends, so under that assumption, SL encourage you to invite your friends to join, I guess, but there is no obligation there, it's all up to you whether or not to invite anyone : )
