Do not "troll" or blatantly attack other users.
Build frequently and create content, dont become a forums lurker. No one likes them.
Builds you deem 'your best' or at least 'not bad' can be displayed in the Gallery. Don't forget to take pictures.
Stay away from the Drama section.
Posting options:

To use these options, simply highlight the text of your posts and hit the button that you want. Buttons that I did not label are ones you will probably never use.
So
Bold text would look like
[b]Bold text[/b]
(I used the "Bold" button and the "Code" button)
To post images, you need an image hosting site. Any will do, but I use
Tinypic. Once you get the URL, copy/paste it into a post and put the Image tags around it:
[IMG][/IMG]
and the image should be displayed. This can be done by highlighting the copied URL and hitting the "Image Tag" button. Use the Preview button at the bottom of your post window next to the Post button to see if it worked.
PS: If you'd like to see how I made this post, just hit the "Quote" button on the top right corner of this post.
You can edit your own posts, and you can edit quotes from other people. Try not to edit quotes though.
