Whoops - I really don't post often.  Now that I put my email address right
on top of the message, is my account likely to get spammed?  Is there any
way to change that?  It doesn't get spammed at all, YET.  How rampant are
those email address-stealing bots?

Very likely

Cancel your post and then repost it with a replaced/fake address

You're very unlikely to get spammed from here.  I don't think I've ever 
got spam from my email address being posted on this news server.

The main thing to remember is that this isn't USENET, it's a private 
news server not connected in any way to the seething jungle that is 
USENET.

You could always cancel your post and repost with new ID settings if 
you're really paranoid about spam :)

Wow, it's really impressive. I had visited this stanford guy's webpage some
time ago, and I'm glad he's updated it with some new really cool videos...
everything there is impressive.

Your smoke looks terrific. I suppose it's a 2D simulation, but it does look
nice.

Congratulations,

Fernando
