I hear these are all the rage at 2ch and likewise boards, so let's see if we can come up with some cool ones ourselves!

• Anime = "Faceless Wotaku @ /anime/"
• ASCII = "CTRL+C&CTRL+V"
• Food = "Cooking Apprentice"
• Games = "NAME OVER"
• Manga = "Faceless Wotaku @ /manga"
• Music = "Unpopular Popstar"
• News = "Unverified Source"
• Politics = "Proletarian"
• Requests = "Faceless Begger"
• Tech/IT = "CYB3R H4XX0R G33K"
• Film & TV = "Couch Potato"

> Since you fellas have nagged on about it

Come on, it's a great idea, nagging or not! :D

And I have one edit to my initial suggestion:

• Film & TV = "Alan Smithee"

• Food = "Copper Chef"/"Azuma Kazuma"
• Tech/IT = "Lambda Lambda Lambda" (In greek letters if anyone can find the code)
• Games = "THRILLHO"
• Requests = "Partition"
