Problem: I think there are too many topics to locate the key information that a user wants to find.
Example: Such as what if a user’s problems has already been solve by others located somewhere under this category in forum, he may cannot find it and create a new topic since there are maybe tens of thousands of topics.
Proposed Solution: Add a search box under each category for key words search to locate the possible existed problems.
P.P. Anyone has the great idea about improving this forum could write down with the similar format. So the forum managers may could handle those problems more easily.
