Thank you very much Fernando, I'm really pleased you like it.

I did try this, but it racks up a lot of requests if you leave it open
for a while and you do pay for them if there's loads. I think you get
10,000 a month on the Free Tier, but that isn't that many at one every
10 seconds. As you suggested, it needs to just do it when there's
something pending, then settle down when all is quiet. The problem is
that refreshing the page refreshes the namespace, so you can't modify
the time between each refresh easily. I'm thinking about how to solve
that??

The AWS console always hogs all my RAM. It's not good. I upgraded to
the new look. Now, it looks nice, but still runs like jam.

I have to be honest, you lost me a bit here. I'll have to do a bit of
homework and get back to you. It sounds like an awesome idea, I'm just
not sure how to do it. I might be back for some advice on that one.

Thanks again

Carl
