There are several pathway to connect to Mark:
1. Email (Preferred, generally will respond within 6 hours)
2. Facebook (checked daily)
you can leave me a message there (pls not directly onto wall, thank you)
3. Twitter (every 3 days)
(unfortunately, Mark's working place doesn't permit mobile usage, so a little bit tricky here.
Please leave a voice message first and allow several minutes so that Mark can walk to the parking zone to reply the call)
5. Linkedin (almost daily)
