ORIGINAL: Mode One
Roltech, My response was not in reply to you; but, was a response to the original poster, Rdavico. R/CUniverse automatically places (In reply to) [very confusingly I might add] in the next post no matter if it has anything to do with the previous poster or not!
If you just type in the 'quick reply' box at the end of the page you are replying to the last poster.
If you click the 'reply' icon on the post you want to reply to it sets the 'in reply to' the way you'd want it to.
