The codes are public information and you're welcome to post them anywhere you would like (within the Terms of Service of the board in question, of course), send them to your friends, or shout them from the rooftops if you'd like!
Of course, it's always nice if you give credit to whereever you found the code, be it MouseSavers or another site.
The request I've made, which I think may have confused safetymom, is that my newsletter subscribers not post certain very specific exclusive offers that are clearly marked in the MouseSavers newsletter. The reason is that the companies making those offers don't want them to be available to the general public, for one reason or another.
That's it! I'm definitely not trying to make any secret of the discount codes -- they are for anyone who wants 'em -- spread 'em far and wide!
I'm sure Tay N Evie's Mom posted to be helpful to everyone here on the DIS, and likewise safetymom was also trying to help, but just misunderstood my request about the newsletter offers. No biggie!
