I have some questions:
* I see that the time field accepts a value in 12-hour format. Is it possible to accept a date in 24-hour format ?
* Is it possible to validate an entered date? For example is it possible to accept a date only if it's not christmas *and* if the day of the week is not wednesday ?
* When a form is filled and sent, is it possible to ask GravityForms to send immediately a (courtesy?) e-mail to the customer? For example to tell him/her that "his/her request has been received and that it will be answered as soon as possible" ?
* Is the plugin working with custom smtp configurations? My website is actually hosted on Webfaction, and I'm using another plugin to set a custom SMTP server (that connects with authorized login and password). Will GravityForms work in this environment?
* If tomorrow I'll purchase a single-site license, will it be possible for me to upgrade to a 5-sites license in the future? And how much will I have to pay for this license upgrade?
Thank you very much
