Regarding the English version;
- The plural for 'reply' is 'replies', not 'replys'.
- There should be no gap if you put ':' after a word. For example, 'Statistics of the forum : Main Forum' should be 'Statistics of the forum: Main Forum'.
Another note, your hack is entitled 'Forum statisctics at the top of each forum' but by your coding it is shown at the bottom. I actually prefer it at the bottom anyway.
No big deal. Your English is wayyyyyyy better than my French!
