This one has been complained about before - I didn't easily find the link. Maybe BM can dig it up.

In the meantime, I saved a cache of it a while ago and that link is still working (docdroid). See:

Unfortunately, over time, docdroid has gotten more "spammy" than it initially was. Apologies in advance for any popups you encounter should you follow those links.

yeah docdroid is horrible

Looks like you just print it to avoid all the crap!

Thanks !
