 If you are unsure, it's ok to post here, though, there are few maintainer so you might not get a fast response. 
 
-Ability of maintainers to spend time and resources on project like IPython is heavily influenced by US politics, and the current government policies have been harmful to the IPython Maintainers and Community.
