links are easy, dmastercard.
1) start typing your Agora posting, and then go and get to the text for the link you want to include (wherever that is, e.g. your browser URL line)
2) highlight it, copy it to your clipboard (Ctrl-C on BSOD, Cmd-C on Mac)
3) go back to your Agora posting, and select the text you want to represent the link (e.g. "and here it is")
4) the "chain" symbol will have lit up in the menu just above your Agora post typing - click on it, and paste your link in (Ctrl-V BSOD, Cmd-V on Mac).
Voila!
It's a big help when peole do the link-posting instead of a URL, so that we don't have to ... scroll!!
Thanks for asking.
