Fig1.Home page(create new help)
I think the team's goal of making it super easy for users to post helps is really good. However, this page involves too many checkboxes and privacy issues that on the contrary increase the complexity of posting a help. For instance, how can you calculate the reliable people? The criteria we assumed in our algorithm may not match the user's mind. Neither can we assume that all the friends have SMS and other information included in their profiles. It's also very sensitive to post to all friends' walls. In our first assignment, we tried that and the whole news feed will be filled with the same content. That's very annoying. The checkboxes also have some overlaps. Say if one selected "all my friends"+"reliable friends", same people will be informed twice or even more times. That's even more annoying. Furthermore, the additional "needs quick help" option makes it even more complicated. The text input of estimated time seem useless to me for a quicker help.
Fig2. Overview page
I think it's good. It enhances users interactions and it is engaging. There is a budge reward for the contributions. One thing to point out is the button design. Can differentiate a bit on "refer to a friend" and "help him" and change the button colour(can use CSS gradient and use a milder colour).
Fig3. Shouldn't be duplicated Prof profile pics shown on the same table, should eliminate duplication.
Refer to a friend(only one friend, no option for choosing friends? May use some autocomplete plugins to allow users to select whom to refer to). It seems that everyone can click on the "help her" button without actually really help the person out. There should be some confirmation mechanism to allow the probablers to know whether these people really helped or not.
Awards: I think instead of award by the app, they should allow people who received help to award those helpers. That will be more interactive and engaging.
They may have problems figuring out how to award people, how to fit the needs for users to change pictures, etc.
