Not a problem
I enjoy this website so I do not mind "giving back" by helping to improve it. Also, while I do some contract web development when I can get it, I have yet to get sick of it.
Regarding the "Recent Posts" block near the bottom, it lacks a unique class or id name which would help to clearly separate it from other layout elements so any styling changes would also affect other parts of the website. Although it is also possible to apply styling rules to the
n-th child of another specific parent element, which can circumvent the need for a unique name, in this particular case this would likely affect other parts of the website as soon as you move away from the homepage.
I looked at a demo installation of XenForo and reviewed the "forum_list" template, but realized that I would need access to your "Recent Posts" mod which was not included.
