I didn't try that option(specific newsletters), but I think you could subscribe newsletters for specific topics using Settings page[^]. Go there, Select Newsletters & Emails tab, mention tags in Newsletter topics field which's in bottom of tab.
Yes, there was something wrong with your nitpicking. The name of -this- forum is ANDROID and that means it is a forum about ANDROID TOPICS and if asking a question about a CODEPROJECT ANDROID NEWSLETTER is not about ANDROID who has the problem?
Me or -you- nitpicking and not only nitpicking it was uncalled for nitpicking.
