Just some thoughts suggestions on registration.
The password box is very annoying. it required 8 characters AND requires the excruciatingly annoying single upper case letter (very very annoying) but whats truly annoying is it NEVER tells you this until you do not do it.
IE it should say right up front 8 characters 1 upper case 1 number minimum
I put in a password rejected not 8 characters.
I put in another password 8 characters rejected no upper case
third try I finally got it :-)
Not a big deal but it is annoying :-) if you mistype a password it should ALSO say 8 character 1 upper 1 number to remind the user its that weird password requirement since many times I put in the right password forgetting one letter needed to be upper case :-)
Another small issue.
your captcha does not appear to change. all three times is was a visually different image but the exact same letters. not sure if you were aware of that.
