Hi Aaron, Considering my mathematical background and knowledge and after consulting Kalevi, I have doubt over my ability to work on Symbolic Integration (especially for algebraic part integration). But considering the amount work that remains to be done in the *transcendental part integration* + *Completing the un-merged pull requests* (*by Kalevi and Chetna*) do you think that would be enough for a GSoC project? Since I *don't* want to get into the *Algebraic part integration*.
