To be clear, he was replying to >>444
with the caching issues. Something not updating is a cache issue and is usually solved by doing CTRL+SHFT+R in your browser. We can't really fix this, because tinyboard a shit!
As for >>443
, that is an issue we can fix, but probably won't. Our reason being that even though /sp/ is a shitposting board, we don't want it to be full blown spam. I'll talk to the others about lowering the flood restrictions to /sp/ though. It's also a case of having slightly higher flood protection or having CAPTCHA (and we all know nobody likes CAPTCHA).
However, if you continuously run into your post being discarded, wait five to ten minutes before posting again and you should be a-okay!
