Ok, how do you guys 'search and list all posts' made between a certain date to another date. Obviously I cannot do a search on 'SEARCH' since it will display almost every thread in the forum. Thanks

Go to the search tab, then click on advanced search, then fill in the dates

Yeah but I still have to type a keyword which isn't what I wanted coz I want all posts during a certain period. If I leave keyword blank and specify dates, I only get error messages. Thanks anyway.

In advanced search, at the bottom left you have search options. This lets you change dates and search in any time frame you want. You can also only search in certain sections and even only search for threads that were started by certain people or mentions certain people. You can not search a time period with no keywords. You need something in there.
