Top 5 Adjustments

[Invigilator]

So, I qualified for a Limit Hold'em freeroll through the Fantasy Poker thing on FT. The thing is, I have never played limit before. I am going to get in some practice freerolls, but...

What would you say are the 5 main adjustments that a player needs to make in Limit Hold'em, if almost all of their experience has been in NL Hold'em?

(this is just to get my thoguht process going)
