Hey all! I'm traveling abroad to Spain at the end of month until May and plan to use my iPad and MacBook on wifi to speak to my friends and family on iMessage (Skype/Facebook messaging those without). To prevent having messages sent to my phone number as text messages and not seeing them until I get home, how should I configure my settings? I'd also rather not send my iCloud email to everyone tellig them to add it to their contacts. My name is in my email, so they would be able to identify me by it.. Thank you!
