I do
meetup.com meetings. One thing nice about them is that they can
easily export to other calendaring system. They can, for example,
export to my Google calendar. Then my TB Lightning can pick them up.
However they put a URL to the event on
meetup.com in the description
field. This is inconvenient. I'd like it to instead be an attachment to
the event so that I could easily double click it and open the URL. If I
modify the event in TB/Lightning and make the URL an attachment the
modification doesn't work. No, I don't get the dreaded "Modification
failed" message. I mean the modification just doesn't work. There is no
attachment. Bug?
