beedyr - I dislike flash forms too, but *most* IW's only require you to fill out all your info the 1st time you enter, and then just addy or addy & password thereafter.
I go by the prizes - if there are lots of good ones, I'll just C&P my info from notepad - I actually broke a 6-7 week dry spell with a FujiFilm - $700.00 Digital Camera win from a flash daily prize sweeps that required you to fill out all your info *every* time you entered!!!
As to whether more sponsors/JA's are using flash forms? I think like with prizes it goes in cycles.
I avoid certain sponsors/JA's because they always use flash forms & I don't want to win all or even a majority of what they offer - it's up to each of us to decide what amount of effort we're willing to put into it. :sunny:
