I'm unwilling to relocate and/or duplicate the link because of aesthetic reasons and to prevent redundancy in the forum.
I also want to show you something that's probably going to save you a few clicks, which is what Tino and I aim for with our current forum layout. I noticed that the "View posts since last visit" link displays the exact same information as what is seen on the sub-forum pages (e.g., Help and Feedback, Off Topic, Custom Art Shops). Here are some screen shots to show you what I am talking about:
Therefore, instead of clicking on a sub-forum > someone's thread > scroll down to Actions link > View posts since last visit, I highly recommend you just click on a sub-forum and view what's new from that page. Personally, this is what I do to see if there are any new posts or topics in a sub forum. I didn't realize that the "View posts since last visit" from the Action menu did the same thing, but I am somewhat glad that I didn't know about it because that's extra work that I don't want to go through.
