Few questions about the themes functions

Hello,

I’ve tried to search the forum for my answers but I haven’t been able to answer all of them, so I was hoping someone could fill in the blanks 🙂

Top of category enhancement
I’m guessing that the listing stay’s on top as long as the listing is live.
Is there a way to limit the duration of a enhancement?
In my example I would like the listing to expire in 30 days but a bought enhancement to only work for 10 days.

Translating issue
On the front page there are 3 lines that don’t translate. Featured Products, Recently Added and Browse by manufacturer.
I’ve gone over the code on few php files but I don’t find it. If someone could tell me where to translate it.

To The Top or bump up
Seeing this is a popular feature on classified sites and in my case I would like to ad this to a paid enhancement where users can bump up there listings 2 or 3 times each 24 hours. Hopefully someone has done this and is willing to share 😉

Facebook connection
Is anyone that has connected facebook to their theme so users can login and create accounts using facebook. Are there any third party plugins people recommend?

MyCRED or other reward system users can collect points and use them to pay for listings.
I’ve looked a little bit into MyCRED but I can figure out how to use MyCRED reward system
as a payment gateway.

I don’t think I have any other questions, at least for now 😉

Many thanks in advance!
