The installation should work with chmod 0755/0775/0777. The fact that can't detect lang files isn't normal, so here are useful reports that reproduce this "problem" (if this is a problem or just a misconfiguration of my VPS), not ones that tell everything's ok (that's the normality).

Anyway, relax

Let's hope try come here :D

I tried with 775 and 755 too..
chmod -R 775 ....
chown -R www-data ......

Alpha 2. I uploaded everything in a /forum/ dir owned by www-data (that runs PHP) and chmodded 777. Moved /forum/root files to /forum
When I go to /forum/install.php I get the error:
This installer was unable to find the installer's language file or files. They should be found under:
/forum/Themes/default/languages

They're there. I can even access via browser the file (for example) /forum/Themes/default/languages/Admin.french.php (of course a white page, but no 404 error).
PHP logs are blank

Setup:
PHP 5.4.8
nginx: 1.3.8
APC: 3.1.13
mysql: 5.5.28

I think that it's important to understand what implies what. It's important that people know how to protect their privacy. I'm saying this:
if you're concerned about some info, nowadays you have to have some technical knowledge. I don't know the % of gmail market share, but it's huge. Now think about the normal user, they go to google, search for something always from the same pc, than maybe use youtube or their phone to look for a route. Google already started gathering your data (about location too if you use your phone).
Also if you use google without logging in on one of their services, then maybe you login on a forum that use adsense, they won.
What I'm saying is that it's really DIFFICULT to hide.
You should be an aknowledged user to do that! And an aknowledged user would know how to disable this method with the manual way.

I know, I was referring to tracking when I said iframe or JavaScript. I think I know a lot about Google's tracking. I saw 1+ hour of a conference of a guy called Matteo Flora, who studied for a while Google's tracking methods and published a lot about it. Summing all Google's method to track users, he ended up that 99,7% of all the websites are "analyzed" by Google in some ways (Analytics, Adwords, google DNS, Firefox's search bar and a lot of others). So, it's almost no info for Google that X user admins X forum, they already know it! And, likely, in the domain WhoIs there's also your home address :P

You don't need to have sendmail() enabled or postfix/exim installed.. and it's more modern than email links (that look so.. old style! :P)
For the user POV, he doesn't need to remove the emails from his inbox! If he logs in often he would have the inbox full
