Manuel has a point... Child-boards are less visible than full boards, so some people may miss it in that format. maybe a full board would be better, however, it is possible to start it as a child-board and convert it to a full board later, or vice versa.
People do still post technical threads int he main board.partly because of how the tech board is named (I would have preferred 'Technical Topics & Repair Assistance', as the way it stands, it looks to newcomers as a 'help me' board, but not a developers area) and then mods move them on occasion. This is mostly new members,who usually are corrected by FW staff and then know what to do afterward.
I actually wouldn't mind some system-specific bards in 'other gaming' either; at least, classic gaming boards that are in some way related. A SuFami
area, for example, would be a positive addition, and having a dedicated NES discussions area wouldn't be a horrible idea.
I would also say that having a couple non-FC items in a FC B/S/T post should be allowed, but if your post has more non-FC items than FC-items, then you should split it. This would also allow better (aimed) marketing for sellers, and the ability to post in more areas with wares, which gains more attention.
If you want to split up more than one extra B/S/T area, which isn't in any way mandatory, I'd suggest having 'Classic Gen' and 'Modern Gen' child boards.For example, i have no interest whatever in systems made after the Jaguar, but some people ahve little interest in Atari-era and Coleco-era items. This would help filtre down the categories to something practical. I would also say that selling SuFami items on the FC B/S/T board should be allowed, although selling them on the other board should also be alright.
It's mostly a matter of getting PS/GC/XBox items out of the Famicom B/S/T arena. People looking for specific items would do better to post in an appropriate board, as those with such articles would be more apt at locating the posts; this is why I'd suggest splitting it up by one degree further into Classic/Modern goods. For my own business, I define classic as anything released from 1996 back, and modern as anything from 1997 to the present, as this was a major transition point for the polygon 3-D era.
The Jaguar for example, was essentially axed in 1996, and it's the last of the true Atari era. The UFC/N64 was also released in 1996, marking the end of the SuFami/SNES era, and the Playstation, although released in 1994, was not really huge until around the same time. This is why I often deem true vintage and classical console systems to have existed from 1972 (The Odyssey) or 1975/76 (Atari Pong) through 1996, and those are the years that I as a seller cover (although I go back to the 1920s with audio & radio gear, the 1950s with television and video equipment, and the 1960s with computer systems).
Categorical boards help both sellers and buyers alike, although I do fully understand the trouble cause by excessive boards in terms of moderation and cross-posting...
