I prefer to have not too much banners (except then from a person that is so kind to host us ), but I have no idea how the leaders of the XOOPS team think about it.
Regarding iMenu, I have no way of knowing. It doesn't come with any information. The version number, 2.03, might lead you to believe that it is made for the same version of Xoops. But is the difference between XOOPS versions 2.03 and 2.05 so big, that it would affect the module installation procedure?
I decided against releasing my modified version to the public as it would further muddle the issue of what Wiki modules were available. However I am happy to furnish it upon request. Send me a PM with an email address and I will send you my modified code.
