Being to the West of Offa's Dyke* I had to answer a question about whether I speak Cymreag. No guidance on fluency, though. I did the Mynediad (entry) course four or five years ago, and have worked through Say Something in Welsh Course 1, but am about as far from fluent as it gets.
I've provisionally ticked the boxes for 'read' and 'speak' on the basis that I can sort-of-work-it-out-with-a-following-wind-and-and-occasional-dictionary, but not not the 'understand spoken' box as my brain doesn't work that fast or 'write' as I'm not confident with spelling**. Not sure if that's what they're looking for, though. :-/
*At least, I assume that folks in Ingerlund didn't get this question, much as I wasn't asked about my Gaelic proficiency.
**Spelling should really be easier than English, as the rules are much more consistent.
