I can read them, but don't see a way to send a PDF attachment in email. I have Goodreader, too; but don't see anything there. Am I missing something.
In goodreader, go into any folder like 'my documents', hit the 'actions' button on the top right of the screen, select the document and then select 'email' for the many options. Works like a charm
Sorry still in iPhone mode. You need to use the 'manage files' tab and then select the file. You will then be given the 'email' option in the menu. Heres a youtube vid review of good reader and if you go to 2min 15 sec in you'll see him using this section. [ame=http://www.youtube.com/watch?v=uD6DyQkLN2U]YouTube - GoodReader iPad App Review[/ame]
there are two apps, the goodreader and the ReaddleDocs. I think the goodreader is much a better one. You can find out to send attachment with goodreader here iPad 2: How To Easily Send Email Attachment On iPad
