You can change that prompt to never appear. That setting is in the messaging options I think. In the message list, hit the menu button and then select options. Should be in there somewhere.
Is there a way to delete multiple messages at once?
not that I'm aware of, I just turned off the "confirm delete" and just hit the delete button a bunch of times until it clears.. its acutally alot faster than it sounds.

You can delete multiple messages by highlighting them with multi-touch. Using your first finger touch and hold (not click) on the first message you want to delete and then with your second finger touch and hold (not click) on the last message. This will highlight all the messages between. To change the highlight all you have to do is scroll and the Storm will adjust the highlight to include more or fewer messages. Then click menu -> delete.
If you decide you don't want to delete you can click the "cancel selection" virtual key and it will remove your highlight.
You can also click on a date within the message center and click menu -> "delete prior" to delete all message from that day and earlier.

ya... place your finger over the first one you want to delete, and without lifting that finger, place your finger on the last. That should higllight them all
