Ohh I had that problem! The button is at the top left, but it's not there in new posts. You have to go to forum jump (it's at the bottom of the page here), select a section and then it shows you posts in that category, and then the new thread button is there to the left. :) hope this helped!
Thanks she is doing very well! When I first got her I free jumped her for a while and she was terrified of a jump any higher than 2 ft. Now she jumps around 2'8ft with a rider. She is like 9 so It might take her a bit longer to adjust I suppose.
She could be a pure TB. There are TBs which are heavier muscled and larger bodied, especially if they are sprint bred. Here is a pure TB mare I owned, and her sire-- the photo of the mare is from right before I bought her and she was nursing a big foal and not even at her heaviest, but you can see she has a large-framed body and some muscle. Her best races were the shorter ones, and she did the best when she broke first and ran in front-- a true sprinter.
Ok I just remembered there is another TB out where my horse stays and they are the image of each other! Every single thing about them is the same. Same colour even XD Only difference is he is a bit smaller than Lola. And he is an OTTB so definitely purebred....
