You are on the sub forum already. Members club room. It is just that everyone flocks to the miscellaneous news thread within the sub forum because it is simply more convenient to use.
Here's what I mean; which is more semantically rich (never mind convenient)?
"Forum-Top-Level > Members Only > Miscellaneous News == One Yuuuge Thousands-of-Pages-Long-Multiyear-Thread for A, B, C...X, Y, Z"
Or, as is common practice practically everywhere else online:
"Forum-Top-Level > Miscellaneous News > Thread A, Thread B, Thread C...Thread X, Thread Y, Thread Z"
