I have used JustHost as my ISP for years. Previously they would make a current version of joomla available and my control panel would alert me to a new version being available. At some point, they ceased doing that and when I would check my control panel would tell me that I was current. After one online chat and one phone call they told me they no longer do that and it is up to me to handle it on my own.
I am moderately technical but this scares the living daylights out of me and I am not certain the steps I should follow. Any advice would be appreciated.
