Sadly I have come to the conclusion that there is no realistic prospect of my being able to actively contribute to Python development in the foreseeable future given my current pursuits and interests, though I rely heavily on Python both personally and professionally.
As a practical matter I have not actively participated in Python development in some years and as a consequence I don't think I have any valid keys still on record. Nor do I now have any operational OS/2 systems to support the Python port to that platform that was my primary interest and contribution.
I would therefore request that appropriate administrative action be taken to close off any commit privileges previously granted to me that may still be active.
Beyond the OS/2 port, it pleases me that I was able to make several small contributions of more general utility.
While the announcement today of the planned move of the Python repository to GitHub has no bearing whatsoever on my decision, I would note that GitHub's requirement that a person only have one account - to be used for both personal activity and any activity on behalf of an employer - is of sufficient concern to me that had I decided to continue as a committer I would be seeking legal advice concerning my position. I say this as to date I have been able to satisfy my employer's requirements for clear separation of my personal activities, including my participation in Python development, from my activities as an employee. This has been possible by exclusively using only provably personal resources, including accounts and internet access, for personal activities. Such clear separation becomes much more difficult when resources such as accounts are shared between personal and employee roles, especially when being seen to do the right thing is as important as actually doing the right thing.
My best wishes to all who have made Python what it is and for Python's future!
