Hey there uSploit, in terms of posting vulnerable sites, you can only post sites which are meant to be tested (such as our SQLi lab). You can not post sites that have vulnerabilities in them but are not designed for the purpose of testing. We could get in big trouble if we allowed that.
Once things have settled down over here and we have completed updating the site, store, courses etc, I am sure we will also be posting fresh challenges monthly with prizes. That won't be for several months at least though!
Hope this helps,
