"+" character not allowed in email during signup, but allowed laterI tried to sign up with an email address that had a "+" character in the left-hand side, and the ajaxy registration page prevented me from using it. So I signed up with a different address; after signing up, I was able to go to my profile and change my email to the correct one without any problems.Also note that I was unable to report this bug without signing up for an account first. :PPlease, please, please stop trying to do email validation, unless you really actually know how to do it.http://jacobsantos.com/2007/general/stop-doing-email-validation-the-wrong-way/http://blog.sinjakli.co.uk/2011/02/13/email-address-validation-please-stop/August 28 2011 - Aurora00YesReport a ProblemProblemSelect oneOffensive contentIrrelevant contentSpam (pure self-promotion)OtherDetailsYour emailPlease enter a valid email address.Submit CancelContent flaggedWe will review this content.
