That is answered in the first post, and here's exactly what it says:
Submitting a Guide:
You might have noticed how normal people can’t start new topics here. That’s there for a good reason: so only guides can be here, and so only the guides allowed in are to be the only things discussed.
In order to submit a guide, you should post that topic in the forum that it would belong in other than this one. A moderator of that forum will move it here if it’s good enough.
So just post it in some other relevant forum and it will be moved.
