User blog:ANTIBODY/Hiya

Hi im new to this wiki, so i wanted to say hi. I can code a little because I wanted to know how to do wiki stuff before i started editing. I also wasnted to get a badge for making a blo post. I noticed a bunch of people here have cool thingys (sigs? Thats what I heard) that say their name at the end of messages. How do I get one like that ? I am excited to help on the wiki but does anybody know some things i can do? I have just been pressing the random page button. Thanks.
