two recommendations:
1. you probably shouldn't make one-three worded posts all on their own
2. if you plan to make a very short post, and then want to make another post, hit the Edit button in the top-right corner of the post and you can change your last post to include whatever else you wanted to say.
here at the blockland forums, making two posts right next to each other is called a double post, and is generally bad manners. three posts in a row is a triple post, four a quad post and so on and so forth.
