What would be the best way to create a flash application that a client can log
into and have news or other messages posted into the flash document. I have
seen message boards where you can login and post, but I would want the client
(without coding knowledge) to login on its own page and have the text imputed
properly into a news or updates section of thier flash website.

For one example, a client is wants his appearance schedule to beupdated often
but he cant understand about the code required for the "load external text" (ie
<br>[B] ect...) that I set up originally. Thanks for any advice.

You could create a simple WYSIWYG editor in Flash and give your client buttons
for BOLD, ITALIC, HYPERLINKs, etc. and then we they go to save the infromation
you could retrieve the HTML code by using:

var newInfo:String = textfield.htmlText;

Then store this into an XML node or database using somekind of server-side
script.
