Topper,
Instead of making your forum messages "a message to Jim" can you make the subject reflect the contents? This makes it easier for a reader to see what the subject is about and therefore contribute to the thread.
Regarding publishing locally using the Immervision Flash applet, you're right in that it's to do with the local security settings. The help file describes very accurately what it is you need to do, just follow the instructions to the letter and you'll be fine.
