There used to be in the right-hand column of most A|N pages, but it's long since vanished. However, if you want to search Atheist Nexus for specific content, you can use the following search string on Google:
site:atheistnexus.org <search string>
As with ordinary searches, you can surround part or all the string with double-quotes to search on specific phrases. I've used it many times and it works great.
I messed around with XML and other coding stuff here and there - not enought to remember it though.
I sent Brother Richard and email asking if he would add a search box for the group.
I wanted to find a post I submitted ~four years ago about a Fox that gave birth under the deck in my back yard. Maybe I posted it on another site.
Using your suggestion I found my post on Atheist Universe.
Thanks for your help.
That search function on A/N never worked for me, so I always used Google.
There was a time years ago when it did work, and then after some alterations in the general page layout, it quit working. It was around that time that I learned the Google trick.
