In the forum,it seems more similar or same questions apart.so before adding a new thread ,if there is an option to view similar threads, which leads to new thread optimisation. ie, no need for him to create his own thread and wait for answer,he can directly go to the answer if available in other threads..
Concluding with advantages
1. no repitation of questions
2. user can get solution much easier

Already there is provision if we take a thread similar threads are shown..so Isomorphic can reuse this before submitting the thread !!!
