Glad to hear it
I talked to the head mod.
Pointing to the PDF('s) and giving extra information in the post itself would be ok.
If the PDF would be located on google or dropbox it should be ok automatically.
They have the most common sites whitelisted.
If it's located elsewhere and/or if you have some extra questions it's best to contact the mod(s) beforehand.
They might need to manually approve your post in case their AutoModerator removes it automatically.
You can contact the head mod through

Let me know how it works out.
