I hadn't thought of 'for grownups' in that way, but I see what you mean. I've now updated the copy.

The resending idea is fantastic. You could, I guess, copy the message into the send message form and click send, but I'll look into adding that as a native function to the UI as well.

The messages are stored on the server. I am a bit nervous about spam, but I plan to deal with that when it arrives. At the moment only one or two of the emails have been 'spam' (messages with only a single word in them).

I'll also look into making some sort of logo ASAP. Thanks for your feedback :)
