I thought it worked this way before, maybe not.
If no location is entered in the admin for a specific event, I would think, hope, like for the "View Map" link on the front end to not be shown for that event.
I did look around for other forum posts on this and check the Track for a future upgrade and did not see this commented on. I am not sure it this would be considered a bug or a feature upgrade.
If it is not clear, I have some events that are location based and others that are over the phone (teleconferences) so would want to enter a location for some and for others either leave the address fields blank to result in no "View Map link on the front end, or if it is easier to add a tick box per event dialog to disable the "View Map" link.
Thanks so much your plugin.
