I have no idea what the hell that is nor have I heard of it... from what you wrote above it appears that you are just clicking on offers. If you would like to create a content locker you dont have to mess with the offers at all. Now you can grab the offers and use whatever ones you want however you want. But if you would like to use Blam ads for content locking the easiest way is just to create a locker on their site.
There are several types of content lockers you can set up with Blam. First type is a 'java script gateway' you will use this option if you will be placing the content locker onto one of your websites. Next they have a 'flash gateway' this will also be used on your own website, but for any type of flash content (youtube vids embeded on your site). There is also 'BLAMCart' that is the only one I havnt used. This option is really only to be used if you have an actual product, and instead of users buying the products you could have them fill out an offer. The last content method is essentially a link shortener that flashes ads prior to forwarding to the url you have shortened.... so if you give me a bit more info of what your trying to content lock, if you even are? I can provide further assistance. Also feel free to PM me sometimes I forget about active threads im posting in. Take care!
