nd of course the email adress should be encrypted (2 way)
Every day of the week and four times and Tuesday I'd prefer the team that spends their marginal dollar on finding the next marginal reflected XSS bug than the one that wastes it on "two-way encryption of email addresses".
I don't know what Weebly does for appsec (I've never worked with them and probably never will), but if they've spent even $50 on external appsec testing, they're 1000% better than 90% of rest of the applications we all use every day.
