User blog:Peter hookpratt/how do u make a new signature

HEllo Potco WIki

i have been wondering how u make a fancy signature like some users do. when i search the talk pages and stuff i see that some ppl have very colorful and bolded signatures. when i go to my prefrences and type in my signature "Peter Hookpratt" it just comes up plain. is there a certain code or way u have to type it? please help and post below. Thank You
