I advert to some StackExchange proposals which I would like to succeed:

Mathematics Software other than MathematicaMatlab
Mathematics Learning, Studying, and EducationEconomics
Finance | ♦ PsychologySoft SkillsLife Improvement |

After reading something, I spend at least several days for cogitation. Please pardon the delay; I will accept an answer or ask supplemental questions.

I will always upvote accepted answers. Let me know of any oversights.

Since comments are harder to read, will you please to write (edits to) responses only in the Answer?
