Now that I've done that it works great. It seems a shame that the Moodle settings can't automatically pick up the correct url by selecting the name of the external tool. e.g. If I select XOT as shown in the screenshot (the name I gave to the external tool via admin) I still have to add the url with /lti/ appended for the selection of an LO to work otherwise it just takes me to the standard login screen. Not a problem for me but I can see it being a problem where users just put what they know to be the installation url, or no url at all, rather than knowing or remembering to add /lti/. I know this is more a moodle limitation rather than any kind of limitation of what you've developed which is great! <o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='color:#1F497D'>I guess once users know what to do via a guide or something then they should remember and I guess in an institution it would be worth customising the help for the external resource activity to show what url to add.<o:p></o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='margin-left:36.0pt'><span style='color:#1F497D'>I can see awareness of LTI growing quickly over the next couple of years especially where Moodle is used as the VLE.
