You can contact me by mobile phone (+44 7840 191336), skype and email, with the option of encrypting email messages and other files…
Please note that my mobile access to the internet is on an ad hoc basis. Also, whether mobile or static, I limit message notifications so as not to be distracted from work.
For real-time communication I recommend the telephone and skype. It’s good to talk.
You should also note that voicemail is for the most part inactive on my mobile phone. Email and SMS may be used in lieu of voicemail, but if you must use text messages to contact me, please provide an email address for reply.
Whenever I am incommunicado for longer than a day, there should be an email auto-responder in place to inform you of this.
