At the bottom? Thanks - will check.
Are you referring to the Browse Routes page? The share icons on this page have now been moved to the bottom of the page.
Regarding route tags, at the moment tags are only for your personal use for filtering routes on your My Routes page, however we are planning to extend this at some point so that you can share a list of routes with a specified tags.
I have read the FAQ about sharing routes (via the Filter page). That does not seem to work as there are no Share icons (Facebook, Twitter, etc) visible anywhere on the screen. Also, weirdly, there does not seem to be a filter on Tags, which would seem to be pretty useful.I basically just want to share only those routes with a particular tag.
