If there could be one section on individuals profile page which saves all the updates relating to each and every post made by the individual in its account.
In the present OPEN IDEO website interface, there is one sigle section for entire website update i.e "Activity Feed" It will be the best, if all openideotors have their own updates section on their profile page which will keep on saving each and every comments made on any chanllenge any time by them, or if anyone else have commented on their posts.
This way individuals can keep a track of their posts if any discussion or updats happening on it on any corner of the website.
In my personal case, im finding problem in searching back for my posts, if done in any previous challenges, or if anyone elses comments on it, dosent come to me.
Yes, very few updates comes on my email address but not all.
Its basically a notification section restricted to only individuals updats on profile page
