Why would anyone refuse to use a forum where all postings are in a language that (s)he speaks rather fluently, where his/her questions would be read by a lot more people, many of them also a lot more knowledgable regarding programming with the BCB than the people usually frequenting this board (myself included, of course)?
And then even act as if offended by the gentle hint!?
Native language message boards etc. are either a place to discuss problems predominantly relevant to the place(s) where that language is usually spoken; or are some sort of last effort for people who don't have a firm enough grasp of the lingua franca of the Internet, which happens to be English.
Another reason could be the desire to improve one's language skills, but that usually requires actually using the language in question ...
