This is a test of the quick-reply feature.
EDIT: I posted this message with the quick-reply feature, and experienced no error, erasure, or double-post. Perhaps your problem is related to the fact that you are using a cell phone to post here, rather than a normal web-browser, and your cell phone's browser has a bug which does not support the quick-reply. My recommendation is to use the regular posting reply button while using your cell phone.
If you feel particularly strongly about the issue, you can report the issue on the
Simple Machines Support Forum, providing them with a little more information, and perhaps they can find a work-around for your browser problem in the next version.
