No, I don't post on any newsgroups. I don't like the attitudes most posters on those things seem to have. I've been Taliesyn for around 13 years now, but pretty much just on message boards, BBS's, that sort of thing.
As to the campaign issues, the trick with the campaign is GENERALLY to make solid defenses, THEN worry about attacking. Some missions ("Isis, Hear my Plea") are exceptions, but not generally. Don't forget that units are your best defenders, but towers/forts help immensely.
I'd say the toughest Trojan War one involves the horse, and if you have problems with that, just ask us. Generally, I didn't find any all that much more difficult to the rest, except possibly the absolute final mission. That's understandable, though - the final mission of any campaign is supposed to be difficult, and this one doesn't even compare to how difficult the final missions were in Star Craft, Brood War, or Warcraft III.
