I'm not sure where to give this feedback, so I'm happy for a coordinator to read this message then delete it.
In the section where we learn about months ...
We are told that month names start with a capital. It would be helpful to have the month names capitalised in the Lesson wordlists.
Immediately after the introduction of "mis" ... April, May and July are given as examples of month names. This would be a perfect place to list the whole twelve months. Lists and correct order really help memory (like how it is easier to memorise you multiplication tables in order, rather than trying to learn them randomly).
The names are all capitalised in the explanatory notes and in the lessons themselves.
Duo limits the space available for course notes, so there is not always space for lists and so on. However, writing out your own lists, verb tables and so on can itself be a useful aid to learning.
(Note that mis Gorffennaf - July - is missing from the lessons at the moment due to a typo. It is included in the next version of the course that we are working on.)
There are many online resources with lists of the Welsh months, here is one:- http://www.bbc.co.uk/wales/welshathome/textversion/nw_e_kitchen_calendar_seasons.shtml
Thank you, both. I didn't realise it was a space issue. And thank you for the BBC site - that's just what I need. Thank you for all the trouble you go to, answering our questions.
