I m looking for specific font to create diff. Form. Specially one with a letter in a square. Not on with round corner but the straight one who all square going to be sticky. Any Idea?

Sticky Square? Anyway, maybe you want something like this?
http://www.dafont.com/taco-box.font?text=sticky+Square

I think he/she means something like http://www.dafont.com/springfield-tablets.font or http://www.dafont.com/alias.font

like the taco one but more formal. I don t want anything artistic inside. straight line black border square inside white with conventional font inside for a government form. Thx again for your answer

Softmaker has a few that are more formal like the a_AlternaTitulNarrowedCameo.
