Join 2 seperate parcels, located next to each other?

Hi,
I bought a 512m3 piece of land a week ago, and now upgraded and purchased another 512m3 parcel bordering my first parcel. I see that under About Land, you can join/subdivide in each individual parcel, but I'd like to join both parcels to be a single 1024m3 parcel, can I do that?

Make sure both parcels have the same owner and same group. Edit Land > Select Land. Drag a selection rectangle from one parcel to the other, so it encompasses land in both parcels. Then the "Join" button should activate. Click Join. The parcel settings for the last parcel selected will take effect for the joined parcel. (Ban lists, etc.)

Click on Build button, then select Land tool. Drag your mouse over portions of both parcels. Now "Join" button should be lit (under the More... tab below). Click Join.

EDIT: posted responses at the same time... ceera's answer is more complete

Thanks for quick replies, it worked !

Yes and it's very easy to do. Follow these steps and you should be all set : First right click on one of the parcels, then left click on "edit terrain", a pop up should appear it and may be a short menu that you'll need to extend by clicking on the "more" tab or it may appear in the long version on the first try. When the menu is extended it will have Select, flatten, raise, lower, smooth land etc.. on the top and buy land, abandon land, subdivide , & join land on the bottom. While this menu is open left click & keep holding it down on one of your plots and then drag the yellow box by moving your mouse onto the other plot. Let up on the left click and then select "join land". Should be as simple as that, if you have problems feel free to IM me in game. Best of luck with your new land.
