# When could a "tag" become a "stack exchange community"?

Initially, I will give you an example to understand my question: e.g., the tag r has many questions in the "Cross Validated" community, then sometimes new users ask questions with content about a bug in R, or something about R packages, and we know that questions with this content are being closed frequently, as was discussed in this question Should most R tags be replaced with package tags?.

So when a tag has many questions that are considered off-topic by the Cross-Validated community, is that a reason to consider creating a new site, & how would we go about it?

• I am really struggling to understand what you mean by your last sentence (So, when a tag that have a many question which fleeing of the community focus can be another community?). Can you please try to formulate it a bit differently? Right now it is very difficult to understand. Oct 14 '15 at 9:00
• I think "fleeing of the community focus" is an over-literal rendering of "fogem do foco da communidade" - not clear English, as @amoeba says - so I've edited your question. Please edit again if that's not what you meant. Oct 14 '15 at 11:01
