Singular and plural in post/thread count

The count of posts and threads in the list of forums only use the plural form.

In Spanish the correct form are:

0 posts. - plural.
1 post. - singular.
2 posts. - plural.
... - plural.

I think when there are a variable number of items should be used plural and singular variables to make a correct translation.
