'ZMail' is Zetapets way of mailing other members of Sentrion. This is a more personal form of communication rather than the forums since it's one-on-one rather than everyone viewing what you've typed.
To zmail someone you can either click the 'zmail' option beside their name on the forums or go to their profile. The profile option looks like this:
Left to right: Zmail, Zpal, Swaps.
Zmail: Zmail the person.
Zpal: Make zpal (remember they have to accept first before they're added to your list).
Swaps: Trades this person has at the swap centre.
I'd recommend you zmail someone before becoming zpals.
After you select 'Zetamail' from the sites menu you'll get an option menu like this above your current zmails:
Inbox
Shows you your current zmails. You can have up to 30 at one time, at which point anyone trying to zmail you will be told your inbox is full.
Compose
This is where you send zmail as shown below:
It's pretty simple. The name of the user goes in 'To', the subject heading in 'Subject' and you type your message in the big '>Zetamail<' text area. When you're done select 'Send Zetamail'.
Zetapals
Your current and pending zpals list. Zpals are shown at the top, with ones waiting for approval at the bottom.
Now lets have a look at the zpals section. I'll use two people from my list (with names blocked out of course) just to show you how it looks and the differences:
Orange: Username and Real Name
Pink: Age
Purple: Gender
Black: Country
Red: ZMail Person
Green: Accept Request
Blue: Reject Request
Both the people above have the age '55' because they joined before Zetapets started asking for your age when you sign up.
You'll know when you've been added to someone's zpal list when you get this event at the top of the page:
This means someone has added you to their list and once clicked on, you can either accept or reject, or even come back to it later.
Blocklist
If someone's hassling you there's always the option to block them. If they're breaking any rules you can report them, but otherwise if they're not this is the only answer.
The blocklist is shown as below. I currently have one person blocked, but have edited the name.
Options
This pretty much explains itself. You have three areas you can select 'Yes' or 'No' to.
Accepting forwards means you can accept mail someone else got that they forwarded on to you.
Accepting zpal requests means people can add you to their list.
Accepting mail from zpals only means other people on the site who aren't on your list can't contact you by zmail.
