Guys, why u stop posting?
This is such an interesting necro thread!
Valloric somehow manages that my eyes don't glaze over when he explains stuff about xhtml and such...
Anyway, Sigil rules and ID CS5.5 sux
ID5.5 It lets you format away without warning until you've overdone it and then just crashes on epub export :P
No wonder that old prick Jobs is kicking Adobe to the curb.
Sigil should cost $500 and ID be freeware... but everything is upside down on this lost planet in the boondocks of the milkyway...
