If you notice the little gold coins after gold, you can click them and a little box will appear, the "Quick Send Forum Gold" box.
It asks you how much gold you want to give, comments, gold password. This is really helpful when you want to stay in the thread that you are in while paying someone.

Now what if you need to pm someone, telling them the game name and password in which to meet you for a trade, a quick hello, whatever.
I find it a pain to go through the steps to pm them, clicking back a few times and then having to refresh the page.

This would make it so much easier...

A "Quick Send Private Message" box.

You can enter the Topic...
The quick little message...
Then just click send!

Just like the "Quick Send Forum Gold" box but for Private Messages.

I voted no - mainly because it isn't much of a hassle to PM people - you just click on the two people under contact, it takes you right to the page, or if anything, you can open it in a new tab (click on your scroll button on the thing you want in a new tab to open new tabs, or press ctrl and click it)

Thanks for your opinion

You already can do this; shift click the PM icon above the gold icon, and it'll open a PM box to that user in a "new window". Send your PM, close the window, tada, done.
