How does one go about sharing a link?

Your shared links are on RP. I just found them.

When you're typing in a topic (i.e. a "tag"), wait until the pop-ups appear to select the most appropriate tag. If you go too fast, you'll key in a phrase that isn't an official tag, which will inadvertently reduce the post's visibility on the site. For instance, we have a tag for "Inspiration", but not for "Inspirational Speeches". I just included the "Inspiration" tag onto your shared link about Reagan. You used "Inspirational Speeches", but that isn't an official tag (although it may eventually become one if others use it enough). That may be why nobody has replied yet. I also added the "Ronald Reagan" and "Peace" tags.

To tag people, type the @ sign and the beginning of someone's name, and a list of members will appear. Select the appropriate people from there, and they'll be tagged in the post.

I also had to learn how to do it, alternating between using the app on both my wife's iPhone, as well as Android tablets we have, in addition to the site here...I needed awhile to learn how and where to paste links in, sometimes, the links don't load visual imagery from a given website, if there are extraneous characters in the URL hypertext link address, one occasionally has to edit those out...the specific rooms to send a given link to, those I also needed to figure out, I still haven't quite figured out how to add a new topic for a room, I've seen the option for that on the app, I've tried it a few times, I think I'm still doing that aspect wrong...sometimes, when I can't get a given link to load, I'll send it in under the update tab, asking admin if they can assign it the right way, explaining I was having trouble loading a given link...also, on the website, on our PC, which I'm on at the moment as the Android tablets I have basically conked out, I also find quite useful being able to correct errors by using the edit feature, as the Android tablet and/or iPhone keyboards unfortunately tend to rather clumsy at times, just a few anecdotal observations I figured you might possibly find useful....
