I don't know, I think it's just starting to clutter the forum up now. It's not worth a whole new subforum just for one person to say hello and then never post in it again. After a while even the older members who pop in to say welcome will become apathetic and it'll be a ghost town.
I also personally think a lot of the PC hardware forums should be consolidated, such as General Hardware, Overclocking & Cooling and Laptops etc. Apple Hard and Software should be consolidated and god knows why the motors and sports forums were split up.
OCuK Matters can probably go altogether.
I just think the entire forum has way too much clutter or is categorized way too narrowly into too many separate things needlessly.
