I'd rather software chats not be on Discord, but that said I've found the forum feature quite helpful for help channels. You get auto-search for the topic as you type out a title, and if you don't see what you need, you can turn it straight into a topic. It's a lot better than the old system of posting into a rolling scroll and hoping one of the regulars is around, and that you're not asking a question which should be in the docs but isn't (and therefore gets asked an annoying amount of times).
