The search here is having issues so has been limited to just one year. It is also a huge data base of previous posts for it to search.
A good way to search is go to google.
In the search bar type site:newagtalk.com,then something about the subject you are searching for then + your user name (or the one of somebody you are searching for a post from)
This should narrow it down for you. It's often helpful to try and make your posts here with something unique in the subject or add keywords to them. That makes it simpler to find them later.
As an example this would be for something of mine as would be typed into a Google search.
