Could you indicate which Forum Topics listings are "Pro-Members-Only", please?
...But there's nothing on the "Posts & Topics" listing to indicate that it's thus restricted.
Once the category really gets going, I fear I'll find myself fruitlessly clicking on listings like "Wild Party at ewilhelm's - Naked Robot Pictures!!!", and that I'll ultimately wind up in a great big ball of Naked-Robot-Picture-deprived frustration.
Ironically, the only reason I haven't become a member yet is that I don't want the "Pro" badge all over my screen name, avatar, and Instructables. Since "Pro" badge can and does appear in any number of places where, In My Extremely Humble Opinion, it is not particularly useful; could you please also put it in a place where I, and perhaps others, would find it quite helpful - to wit, on the pro-members-only Forum Topics listings?
(Note 1: something about this business of the "Pro" badges seems to have put me very solidly in touch with my Inner Petulant Whiner. I've tried to keep the whiney petulance to minimum, but do also offer my apologies for those bits that seem inevitably to leak through.)
(Note B: Any and all references to festivites hosted by ewilhelm, and/or to photographic evidence of Robot in a state of deshabille, are purely hypothetical. Any resemblance to actual robots, people, or events, is entirely coincidental.)
