You may post only 3 poems or stories each calendar day.
The only time you'll see those words that way is when you are posting a new topic in a poetry forum. You won't see them when you post a new topic in a discussion forum (like this one), or in a workshop. Nor will you see them when you're posting a reply, even if that reply is in a poetry forum. Those words, in short, need to be taken in context.
There is a long-standing tradition in the forums of poetic repartee within a thread, where individuals reply (usually poking fun at each other) in verse. I suspect we could find threads in the Archives with dozens and perhaps even hundreds of "poems" sprinkled throughout. Our rules were never meant to limit how people can reply. We're just glad that they do.
Nonetheless, you are probably right that the three-threads-per-day could be more clear. I'll work on that. In this case, however, it certainly doesn't apply. Tom Zart is making his own threads load more slowly and using forum resources to no good purpose, but he's really not hurting you or any other Member. It's not a big deal.
