BlogAds, not exactly easy to use

I've been using BlogAds for a while but I should say that even though it's a great idea, it has a poor implementation.

I can't write a review on it right now, but what frustrates me most is the fact that I can't edit the ads people have submitted to me. For example, I can't accept some of the banners people submit either because they are bigger or smaller than my standard size, or they are simply ugly.

So if i want to change the banner with a new one, designed by me, I have no choice but to send the banner back to the owner and ask him or her to replace it with the older one. The same thing would happen if I want to change their wording a little bit.

Moreover, eventhough it works fine with Unicode, but since the default page encoding (maybe on the web server) is set to something other than Unicode, every time you want to change or see something in Persian, for example, you have to change the page encoding to Unicode -- it's such a pain.
