Thanks for pointing me where to look for the language modules, I kinda thought maybe I was overlooking something obvious. I'm still pretty new to XOOPS, that's my excuse (sheepish grin).
So in this case, it was my oversight in not looking in the obvious place, and once there I found the files well organized.
I still think the modules listing could be better organized. It's very good of the authors to release their modules etc for the rest of us to use, and imposing some naming conventions may not be a good idea, especially as in some cases the category or main keywords may not fit some narrow definition.
An alternative suggestion, maybe a list of alias names that point to the modules, then these alias names could be categorized, eg
calendar modules
menu modules
Unfortunately, I don't have the time or knowledge to do this, but we need to avoid the situation that happened to Red Hat users and RPM hell.
I think that given the ease of installation of XOOPS and modules along with boldly applying OO concepts by the core team and others, we will see XOOPS grow in popularity compared to say eXOOPS and Postnuke etc. so the number of modules will just grow and grow.
