I wouldn't get too carried away with lower branch topping if you are trying to do LST. You kind of want the branches to grow a bit so you have something to tie down, but still grow a decent nug. You could easily fill that tent with three plants. They look pretty happy at this point.
In the post or reply window there is a row of icons. The globe with the chain link. Hit that. It will create a title for you or you can edit it yourself. You can add text at the start or after the URL parentheses. See the black text "First Grow Fail"? That I added after the parentheses.
