[savannah-help-public] how to delete an old news item?

[Brandon Invergo]

Before pyconfigure became its own independent GNU project, it was living
(somewhat awkwardly) in the GSRC source tree. I had announced its
existence at one point in the GSRC news feed. I've just had someone
contact me saying that they found that post via a web search and they
were confused because the source was no longer there. They eventually
found the pyconfigure project's page, but nevertheless, that news
posting was a false lead.

I cannot find any way to edit or delete that post. Is it possible?
Here's the post in question:

Thanks,
