I have checked the site travelpal in detail. The main sections are Touristwiki, blog, destination review, Q & A, Bazar, member, forums and login/register for the users.
The bazar section has item categories and user can contact the seller directly. To view the seller details, user has to be a member first.
Regarding the destination review section, user can post an article for a destination and other member can provide ratings and reviews on it.
Let me know if you have any specific features in your mind.
I would like to discuss with you via skype. My skype is sourav_acumensoft
