Could you expand on this more? Do you mean the character limit on searches ought to be removed?
If so, that was suggested somewhere before. Thing is, I don't know if it could be incorporated or used effectively. I can only assume that too broad of searches would fail to appear. Heck, even when you search all the forums for common four-letter words like "from" or "when", no results for the Forums are found, even though there have been plenty of threads containing both words. If it's not on the list, I can add it, but I'm not sure it can be incorporated.
The post there cannot be accessed by Guests or Members. When it is attempted to be viewed, it brings up the error page with the error something along the lines of "You do not have permission to view that".
I'll add this below Autumn's suggestion. Do you perhaps mean threads located above Pinned Threads, like in the RCBA Sub-forum?
