I obtain copyright permission of all original images before uploading and give people clear contacts to do it. I refuse to install extensions that could clobber the setup (many aren't compatible with postgres). I also make an attempt to contact rightsholders. the only stuff I don't have permission for is a few system image placeholders and the logos of companies. The SGI trademarks are basically gone though, HPE ain't using them.

> If you can find ways to collect and preserve copies of the software, that can be big value. Every version and variation of a title has sometimes been important after the fact. Maybe use archive.org for historical archiving of software with unclear licensing status, and link to it from your wiki, with your wiki providing the background text and organizing that isn't archive.org's strong suit. (I'm not talking about piracy, but just trying to ensure that any copy at all survives, which had been a real problem on some other platforms of this era. Also, it's easier to get a company to say that such-and-such software from a company three acquisitions ago is OK for people to run on vintage boxes and in emulators and museums, than to ask them to find and provide a working copy, which they usually cannot.)

Over at IRIXNet we do have some files and such preserving what's not likely to get us in trouble, but I choose to not deal with copyrighted works on tech-pubs (which unlike IRIXNet is my pet project, not a part of IRIXNet)
