Interesting; I’ve search user names countless times over the years and I just couldn’t get it to work this time. This is very odd. Why does one now have to use this radix thingie, and how did you find it?
If you click on yours or any name in a post it takes to your homepage.

Again, replace the user name after the tilde (~). From there click the “In Forum” link and that takes you to the posts. Further, the link I gave you earlier is the exact link if you search FR by user name (in the drop down under search box).
