Hi there, James!
Yeah ... I know that it looks like the blind-leading-the-blind here ... and it is ...
... but, we somehow usually find our way to where we're going!
I'm sure that the support forum will be very useful! I'll be sure to check it out! Most of us will just have to click our way into figuring out how things work around here. And it'll probably take some time.
With the problem I had with embedding, I found out that it works perfectly well if I'm using Internet Explorer for a browser .... but, I'm a Firefox user ... and for some reason that feature doesn't work with Firefox!
That's not just a LiveCloud thing, though ... I periodically run into that problem with other softwares and programs.
I do like the video you posted, though, as a test!
Oh! And welcome to the board!
