Ok 2 guys already asked me how to attach his/her signature on His/her post.
Here are the requiered steps:
first of all you have upload a picture i.e
www.photobucket.comgo to your profil and click "signature" copy the the link below of your uploaded pic at i.e
www.photobucket.com and paste the "
" link to your signature window and save it.
after that you go to tab "preferences" and change the option "Always attach my signature:" to "yes"
Thats it !
