bool f = true;

private void Form1_Load(object sender, EventArgs e)
{
    wbLoad.Navigate("http://login.uid.me/?site=dmysite&ref=http://mysite.ucoz.com/");
}

private void wbLoad_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    if (f == true)
    {
        if (wbLoad.DocumentText.Contains("Sign up"))
        {
            wbLoad.Navigate("http://login.uid.me/?site=dmysite&ref=http://mysite.ucoz.com/");
            f = false;
        }
        else if (wbLoad.DocumentText.Contains("Log out"))
        {
            wbLoad.Navigate("http://mysite.ucoz.com/index/10");
            f = true;
        }
        else
        {
            wbLoad.Navigate("http://uid.me/logout/?mode=1&noajax=1");
            f = true;
        }
    }
}

Logging out means in most cases just removing cookies for current host. If it’s your case, you can do it by using javascript. Note, that this JS will remove cookies only for current host. You can call it in FormClosing event

wbLoad.Navigate("javascript:void((function(){var a,b,c,e,f;f=0;a=document.cookie.split('; ');for(e=0;e<a.length&&a[e];e++){f++;for(b='.'+location.host;b;b=b.replace(/^(?:%5C.|[^%5C.]+)/,'')){for(c=location.pathname;c;c=c.replace(/.$/,'')){document.cookie=(a[e]+'; domain='+b+'; path='+c+'; expires='+new Date((new Date()).getTime()-1e11).toGMTString());}}}})())");
