IF your semi colon question is centered around email and wanting to send to a group email, there is a cool trick I learned that allowed me to do so and it works like a champ.
1. From a source another than your ipad (I used my laptop) create an email with ll the email addresses you want on the group email to include your email in the cc field.
2. Send a test email telling the group this is a test..(hint:it will save you many curious use tins)
3. Open the email on your secondary source, other than iPad, and copy the addresses you want in the group mail.
4. Paste the full group in the body of a new email to include semicolon and Snd that email to yourself.
5. Open email with group addresses in the body of the email on your iPad.
6. Copy he addresses as one item.
7. Go to our contact link on your iPad and create a name for your list as the contact name.
8. In the newly created contact you may put any info thee you want but in the email section paste the copy fom the body of the email with ALL addresses as the email address in your new contact.
9. Close the edit portion of your contact and open email. In the email address place curor and start typing your new contact and whn it operas like any other contact click on it and it will place the name in the email address location. Sn the email and along to yourself and while a box appears that says you have an incorrect email address go ahead and click no and proceed..Check your work...pretty cool huh? Enjoy.
