Why don't I have a "Word" list?

[songbirdstew]

On my account the tabs along the top blue bar are Home, Activity, Discussion, and Immersion, while on my brother's account there is an additional tab for Words that has a list of words learned and how recently they have been practiced.

I don't know if this was a new feature added on an update but I believe we made our accounts around the same time and don't see how that could be... also the lesson interface is slightly different.

Anyone have similar problems/know why this could be?

Duolingo are AB testing the feature so half have it and the other half do not. Hopefully testing will be completed soon and it will be released to everyone, but i am not holding my breath.

Ahh, darn! That would be useful. Thank you for the information!
