evant,

since we're discussing your grammar (or lack thereof), it's p.s, p.p.s. and p.p.p.s.

p.s.
p.s. means "post script", or "after the script", so "post post script" would be "after the p.s.", etc.

p.p.s.
Totally making fun, don't take it seriously, please continue to post useful information regardless of speling; punctuatoin, or grammer.

p.p.p.s.
Though it is true
