Very nice looking builds. One way to reply without typing is to hover your mouse over the heart symbol at the bottom right corner of every reply. You can click on the heart to give the post a like or click on the trophy the shows up when hovering over the heart to give the poster a thanks. You'll see a black circle with a white x after clicking. If you hover over it it basically say click to remove reaction. I'm pretty new to posting builds on here myself. Right off hand I'm not sure what all the other stuff is either. I believe a star next to a title means you have made a reply in that thread.
