So you get extra XP for posting in the forums?
Hi Daniel,
You get points by successfully completing shops, by doing Opinion Polls on iSecretShop, and for completing courses on iSSprep.com.
As for the Forum, when you post useful content and your posts get up-voted, you gain the Forum Contributor badge, which is a nice addition to make your profile stand out more to schedulers, giving you another advantage when it comes to having your requests approved.
Cheers!
FYI, declining a shop now gives you - 30 points. Must have increased since that above other posts.
