Do not use this tag: questions related to learning the Spanish language (tips, learning materials and so on) are off-topic and will almost certainly be closed.
The tag wiki contains a link to Resources for learning Spanish, but does not tell people where to go with learning-related questions that have nothing to do with resources. Are there any objections against adding something along the following lines?
For questions about learning Spanish that have nothing to do with resources, you can go to Language Learning Stack Exchange.
