I started a new topic in the Trades section, and when I tried to pick a category from the drop down list, it allowed me to select a category that was linked to the sandbox.
(I ended up not tagging it with the Postcards sub-category, which I probably should have, 'cause I wasn’t sure which to choose. I notice there are postcard swaps both in the main category and the sub category).
I’m a bit surprised that nobody report this before! Thank you so much Helen — it’s not something that should have been there.
When I created the category, I wasn’t sure whether to make it compulsory for people to choose one of the subcategories… but now I think it would be a good idea, to keep things tidier. What do you think?
