Well actually you can attach the PDF yourself in any post you make here. This is via the "Manage Attachments" button visible whenever you are creating a post (either new thread or a reply).
Once you are in that page, then you simply upload the file via the BROWSE button (you can upload up to four files in each post) to search out the file on your home computer. Then you click on the UPLOAD button and this uploads the file(s) to the server. The attachment key at the bottom will show you whatever limits will apply to the type of file you wish to upload.
But if you get stuck, let me know and I'll help you out with this. Don't be afraid to experiment. You really can't break anything here.
All I ask in return is to be mentioned in your will for your Corvette.....
