png\" border=\"0\" align=\"absmiddle\" alt=\"Á´½ÓͼƬ\"
onload=\"if(screen.width*0.7<this.width) {this.resized=true;
this.width=screen.width*0.7;}\" /><br />¡¡¡¡<b>Adverment&#33;</b>

that
requires no setup, no configuration, and works even if both users are
behind firewalls. It&#39;s designed to make remote tech support easy.
<br />¡¡¡¡<br />¡¡¡¡Enter your email address to receive a (very
occasional) email whenever I write a major new article. You can
