Either on-site or in chat.
I understand that they are technically classifiable as 'software that can be installed', but it gives rise to un-answerable/complaint types of queries.
Simple relatively abstract example:
I want to do this that is available in current mainline someproject
I can't do it in older unmaintained project
If it were actively maintained my answer would be 'file a feature-request/wishlist bug'
If it's not, where do i go from there?
