Hi, all! I've recently received a few questions about tagging clips on mobile devices. It used to be that this was tougher to do than on a laptop or iPad, but such is no longer the case.
Photos, videos, etc. (aka clips) can be tagged from any device, so please be sure to do so.
However, to tag on a mobile device, you must be in the "standard viewing" mode, not in the "mobile interface" mode. To toggle between modes, just click on the small gear-like icon, usually in the upper right of the mobile interface; then click on the link to view in "standard" mode. In standard mode, the site will appear on your phone just as it would on a laptop or iPad, and you can upload and tag/classify clips as you normally would.
Hope this helps! Let me know if there are any further questions about this. Thanks!
