The original concept behind these was to give an alternative to LLs that matched the hosted galleries that TGPs use - and that was it.
I do agree there are other reasons to build hosted free sites of a different type for entirely different purposes as some programs have with their zipped sites etc - but this type of free site we are concentrating on here is really the LLs "filler" sites just like the hosted gals and thats really it
