How to Select a Forum http://forums.adobe.com/docs/DOC-1015

Welcome to the Forum, however this one is for discussing, well the forums, themselves.

I would Move your post, but am not 100% certain, where it should go.

I think that you want this forum: http://forums.adobe.com/community/adobe_reader_forums/ios?view=discussions

but maybe others can direct you. If that IS the correct forum, then I, or someone else can Move the post for you.

Good luck,

Hunt
