I am currently testing some backing up some of the Newtek forum pages, with the help of winHTTrack.
Currently I do not get the full depth scan of all pages in a section, while I can go in thread by thread and save a thread, which should save all pages on that thread, including images embedded in that html file, full images may not or may be stored locally on my computer depending on if they are attached on newtek forums or other external sources.
Need to check up more on winHTTRack and how to scan save all pages the best way though, theres a lot of settings to adjust how it scans and saves links and images etc.
