All the above being said, I hate when programmers stands with 90's technology (namely "tables for everything") when using divs is way better, faster and easier to modify as you wish. I've made a couple of VB mods where I replaced as much tables as possible with divs because it was absolutely nonsensical and way too limiting to use those motherfucking tables. Sorry: I mean tables into tables into tables into tables (believe me, as ridiculous as it sounds, that's the way VB is coded)
