Hmmm, I believe that I tried the edit that you describe but unless I'm mistaken, it still came out as a separate post. Then again, I often write while sitting up in bed and sometimes a little too tired to stay properly focused. Thank you for the suggestion. I'll try it again.
As I type this post, I'm realizing that this is the first one that I have written using the "real" version of iRV2 as opposed to the app version and i notice that the send button on this version is well out of harms way. Problem solved.
