As seoagent mentioned in another post, it is very important that "Bump your ad" button to be visible just by poster, maybe right in loop ad listing, not in single ad listing. The same importance is to be compatible with sticky on top plugin and to respect time of expiration. So, I think is important to check compatibility with another plugins and to give users posibility to use it without problems. I say this because I bought from you another plugin, Advanced search premium plugin, but, unfortunately this one works inependently and not cooperate with "Classialert" plugin, that make "Advanced search premium" plugin useless for me.
