Good job with the recent site upgrade, the forum looks modern and fresh. This is just a small suggestion but I think the "like this" button on the site could do with a visual update to make it stand out a bit more as it currently looks disabled or "greyed out." Took me a day or two when if first appeared before I realised it was clickable. The placement of the button itself also looks somewhat disjointed to the rest IMO, especially when there's a signature present.
Some ideas below.
