Hi.
Sorry that I dont post this in Adsense section, but it is now closed for review.
I created blog in my native language some time ago (about 5 months) and put addsense on it, i have posted there 300+ articles, but its not going good for me so I want to change language to english. And the question are: can I leave old articles in my native language, and post new articles in english, or should i better delete old ones ? I am asking this because I dont want to risk my adsense account.
