I know its a pain to have to fill in all that info to report the RMT. I found a macro that helps a lot. In case you're interested, here you go:

/echo World: Your world
/echo Date: Put date in when you log on
/echo Zone: <pos>
/echo Character Name/Details:
/supportdesk

Then just copy and paste this into the form, and then copy and paste the RMT Ad you received underneath. It's not perfect, but it really decreased the amount of time it takes to report it, for me anyway.
