Newb weight questions

[BPH]

New to the Coop Ad Network....

Does the weight decrease as your ad is displayed?

Is the weight drop down basically how many points you want to "pay"?

If a site is using just text links, does your description just get lopped off or do you need to specify a descriptionless ad option?

Your user weight does not change unless it's revalidated (which happens often). The weight assignment for an individual ad is you allocating your user weight between your ads.
