FYI: It is still not possible to download pipeline attachments from the old forum here on our new forum. Basically this means that on older (~pre-Dec 2015) posts/threads *.cp, *.cppipe, *.cpproj files that are attached usually will not download (the download may appear to work, but display blank depending on your browser). Yes, annoying. But we are working on it. Migration to this new Discourse Forum has had most of the bugs worked out except for this one. Attachments since the transition should behave properly. If you are really desperate, we may be able to manually retrieve these from the old phpbb forum in the meantime, but we can’t promise.
Thanks for your patience!
