A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
► complete the sentence: my question is about...
► use tags that describe things or concepts that are essential, not incidental to your question
► favor using existing popular tags
► read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
► combine multiple words into single-words with hyphens (e.g. windows-7), up to a maximum of 35 characters
► creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
