could we have sub-forums?

because we are able to title different sections, i look at each forum sort of like a "sub-forum" already.

for my video game group, i have a general discussion section (for general news and info, group announcements and chat) a platform-specific section and a section for other stuff (celebrations, entertainment and jokes). i have 11 forums total, split up in 3 different sections.

just tryin' to help.
