I have to agree with David on this one. General can be used to post links to Linux fun sites. It having its own forum would only invite unwelcome posts, links, etc. General is just fine for this as we don't need another separate forum to moderate, etc.
About the other one, that is the sole reason we made the Success Stories, to post any type of Success with Linux, as if you just converted from Windows or got something as simple as Flash working. You can even post small howto's or tips as well there, as they are very suitable in that forum.
I really only see your requests as being fulfilled really. If we break down the forums into too many categories, its only going to cause confusion, more double posts, etc.
