Are you talking about a dedicated sub-section within the how-to for his posts specifically? Or a thread where all of his posts are linked? I'm not 100% following how they would be organized / separated.
Typically we separate the how-to section by sub-section only (interior,exterior, etc.) not really by the author who created the thread(s).
If you have a "favorite author" for certain information, you could use the advanced search function to further filter the general search results to your liking.
For example, I performed an 'advanced forum search' and came up with the following realativilty quickly:
Search Criteria I used:
User Name: dogfish246
Select "Find Threads Started By User"
Search in Forum(s): How-To
Show Results as: Threads
Search Results:
How-To Threads by ChrisFix
That provided a filtered list of his 46 "How-To Submissions" on this site relatively easily without having to manually search through the complete 'how-to' section for a thread of his.
