Thanks   CalTheGreat, 

 

I could not remember who posted it otherwise I would have done that.

 

Also, I did not remember that I had responded or else I might have found it that way.

A suggestion of how you can track the posts you are interested in:

 

I use my watchlist but I am often afraid things will fall off the end of it. I think only 25 posts are stored there.

I have other methods of trying to keep posts that I am interested in too.

 

BUT a method I have only just started using recently is to take a pic of the post then private message myself.

I send myself both the actual address of the post as well as a pic of it. 

So long as I remember to do it (which I didn't do here) it works really well.

 

Thanks for all your help guys and girls. :)
