Although I'm seriously loling at you right now, I'll help you.
I can guess you are from ROBLOX, the game in which you use a custom browser to join servers. Blockland works differently. You just download the game, install and you play. You have to buy a key for $20 one time payment to play online and get out of the demo restrictions.
1. Go to
www.blockland.us2. Download the demo.
3. Play around in it.
If you like the demo, go to step 4a.
If you didn't like the demo, go to step 4b ahead.
4a. Buy the game at
www.blockland.us/index.asp?p=Store5a. Wait for your key to arrive, and enter it into Blockland.
6a. Enjoy the online world of Blockland!
4b. Remove the game from Add/Remove programs.
The demo restricts you to 150 bricks and only lets you play alone. You can share one key with a sibling who lives in the same household as you, but you'll need to keep the same name and you'll need to computers under the same household.
It is EXTREMELY advised to not give away your key to people across the internet. If you do, then a lot of people will be trying to play on your key and you will never be able to play.
