Sounds like you have "hyperlinking" turned on in whichever device you're using.
I don't know of any such capability on this site, but you might check with Slab to be sure (or to find out how to turn it off, if that's what you want to do).
Are they just showing up on your screen when typing in a message, or are they actually showing up that way after posting ?? I think I've read all of your posts on this forum, and have yet to see any hyperlinked words appear.
