Hadn’t noticed the grey pencil (?) symbol before today. Has it always been there? What does it signify?
There’s one on every one of the course tiles on my homepage, regardless of whether or not the course is complete or there are items to review. They don’t show on the corresponding tile in either the course page or course catalogue.
I just checked my Dashboard. I see the gray pencil on Spanish courses and in a couple of minor categories. The German and Turkish courses still have their country flags. Perhaps the Memrise staff is editing some of the category icons?
Thanks @Kaspian. I’ve just checked my other categories (should have done that before! 
) and they are showing their usual icons, too. Maybe the grey pencil is the ‘default’ icon and it’s just a temporary bug which caused the Spanish flag to drop off.
I can confirm that the gray pencil is the default icon, it used to be the icon of course that didn’t fit into any popular category I once took. (I think it was either Harry Potter spells or guitar chords, can’t remember.
)
About the Spanish flag being renewed, I think Lien mentioned in another discussion that they were splitting up “English” into “British English” and “American English”, maybe they’re doing the same thing for ‘Spanish Spanish’ and ‘Mexican Spanish’? (Not sure, just a guess)
Edit: I looked it up again, the courses were an HTML 5 and a ‘Natural Wonders’ course
Also, I found the discussion where Lien said they were splitting up the English courses:
Then Chinese/Mandarin and Chinese/Cantonese can’t be too far behind 
There are no grey symbols on my home page which comprise mostly French courses.
I have them on this course and this course, but none of the others (Geography, Finnish, Czech, French. and Russian).
Thanks everyone! If, as seems most likely, it is part of some ongoing action to differentiate between Spanish Spanish and Mexican Spanish, it will be a good thing. Let’s see what happens next. 
I just checked and yes, the courses are now differentiated.
But so far, there’s only one course teaching Mexican Spanish, all the others are in ‘Spanish’ for now. I wonder if they’ll ask the course creators to specify or if ‘Spanish’ will remain the standard category.
Edit: Why do I always forget how to make pictures show up properly? 
But it should work now…
The symbol actually looks like a blank label to me. 
I noticed it a few days ago on my English course and wondered then if it was new. All of my Spanish courses have it and also my “math” course which used to have the pi symbol.
i see that happening with portuguese and spanish courses, with cantonese, with classic languages except ancient greek and latin (why that famous but not so pretty pot was chosen as symbol for Ancient Greece, only memrise knows; also the symbol for Latin does not make much sense)
Thanks again everyone. Yes, it looks like they’re doing some housekeeping with those labels.
I’ve had a look through the course catalogue now. I should have done that before starting this topic.
I’ll close it down now. Move along, please, everyone. There’s nothing to see here!
