If you have questions about how to use WordPress or need help with WordPress-related hacks and themes, then post away.
If you want to argue, complain, flame, scream, whine, boast, laud, lament or otherwise make comments about issues that are not support requests, then use your own blog.
Your site is your voice. This site is a resource for users needing help.
I have a quick "Delete this Topic" finger, and I'm not afraid to use it.
