Hi,
I having been using twitter now for a couple of years and recently also signed on through tweedeck. On my desktop for uploading images it gives the choice of which service to use and as I have been using twitpic I naturally gravitated to that.
Last night I uploaded a photo from my Android phone and it auto selected yfrog, can't find a twitpic link on it so went ahead with the upload. I then got your confirmatory email asking me to confirm my details along with the usual fuzzy two re captcha words to translate. Well I have been doing this for years and occasionally get one wrong, but with your site I seem incapable of translating correctly the words and so after the umpteenth attempt I have decided to stay with twitpic as I have spent more time trying to input to this silly service than it clearly deserves. If signing onto your service is as difficult as this for others I wonder why I ever see any photo links through this service!
Regards

PS: these were the words that appeared after the input of the email that had to be input correctly for the email to be sent and guess what, I did it on first attempt, so WTF is wrong with your sign up confirmation service?
