Well actually, I think that is a bit unfair. You do not get to thousands of posts on any forum by being a forum vampire. Diva has put in a lot of time helping people. And is working on several mods for upgrade to 1.5 that will be released when they are ready.
The thing is that this particular thread is about mods not being visible in admin. If you are having problems with that issue then this is a really good place to post your questions and people will do their best to help. If your question is a more general 'Why doesn't this module work with 1.5?' then this thread is not the right place for that kind of specific advice because to answer it people need to have specific knowledge of the module as well as knowledge about the changes in Zen 1.5.
There just is not a simple answer to the 'why doesn't this work with 1.5?' however much people want there to be one and at times have suggested that there is an answer that is somehow being hidden from them. It depends entirely on the module.
