the ICS icon points to an .ICS file which is not what I want, I just want to send a link of a web page about one session then say: hey look this, interesting huh, blah blah blah. and he can also navigate to other sessions or pdc pages from there.

now I can only send others the link of the list then tell him the category and session name and ask him to find that session in a huge list by himself, duh.
