Not every piece of information can be found in this forum, you can't rely on this forum only to grow your knowledge. Don't deny other sources to improve your knowledge! It is true that this forum has many sections, but most of the sections are related to crypto and forum topics. Only in the off-topic section can be found non-crypto/forum topics. But I think they are rather limited.

If you want to focus on improving your written or spoken skills in English, this forum isn't the right place. You can visit English course sites, or any sites that provide specific information about learning English. As far as I know, this forum doesn't provide a specific section to learn English abilities.
