the link to the left, 'Module Development' is also very useful.
http://wiki.xoops.org/wakka.php?wakka=XoopsModuleDoc << straight link
i find it very useful to look at an existing module to figure out how it all works. also, if you're using an existing module as an example, and you see it 'include' another file, then look at that file's contents to figure out what it's purpose is, what other functions are available to use, etc etc
it's been difficult for me to get used to the XOOPS way, but i'll try to post something in a thread or in the wiki somewhere, for tips
are you coding from scratch or porting a module from another cms?
