To contact us, the preferred way is the forums.
There is a whole lot of people who will be able to lend you a hand (yes there’s the author, too).
You can report bugs as well.
In order to give the best support, before asking, have a look first on the wiki and do a quick search on the forums as well. If you don’t find what you need or you still need some help just ask, and we’ll be glad to help.
If you really need to contact the author privately you can also use our pretty contact form.
Please remember that the contact form is not for technical support: using the contact form won’t mean a faster reply, if the author is busy (in fact, it will probably mean a slower one).
