For the most reliable means of Internet contact, one should consider using my Email address. Use of social networks to carry on a conversation will find that I will not rush to the site to respond to a 3-word reply. As a habit, I will check most social networks I have an association with once a day. This frequency will reduce when there is no productive activity going on.
If you do decide on email, and if there was a need to send a large file, I will upload it to fsp.cc and only to there. You will be able to select the link to download. This will reduce the demand for servers and eliminate the chance of bounce email due to size limitations.
