I would like to suggest a search feature to be added amongst the various threads and even Messages and BackAlly.

The new search would read through articles and messages returning likely results from a key word or phrase in "quotation". 

Allowing multiple key words would increase the match and returning the search by match% 

Often times I can remember a conversation or comment but not by who so or where so gets hard to find. I know I can use a search engine to help but on threads but not messages.
