I think a banner might overcrowd the top. It’s nice to have it for a short time message but tester posts are fairly regular.
Personally I’d say try it with just pinning them in the category and then see what happens. We can always go back to the old system if it doesn’t work.
Absolutely think this will work. I’ve been keeping an eye on the sex toy tester page to see when it changes, but only just realised there is a post that communicates when to update the sex toy wishlist.
As it seems the sex toy category is a big interest for most here anyway, I think it would work well.
There was one on Fri/Sat (because I forgot to take it down), it was the big blue thing at the top of all the posts. I can pop an example one up today to see if it helps?
