That would be great - if it is more than 128KB then we may have to try something different - but, go to Cookbook Contents here:
http://www.forumthermomix.com/index.php?board=52.0 and then
New Topic In the Subject place Fast and Easy or whatever and then down at the bottom it says -
Additional Options... Click on that and a box will come up with
Attach: and you can Browse to find the file to attach.
Alternatively, and may be easier? just open the .pdf file, go to Tools on the top line and then Select Tool and Highlight the contents and Copy and Paste into the Message box.
Good luck, and THANKS
