That's because many of us were occupied with school and work among other things. I haven't the same time as before to map, so when I can, I do some mapping.
However, you can help us in many ways. Just two things before the suggestions:
* If you want to contribute, GPLv2 is the law here. Just to clarify things: if you release something, then you should release too the stuff you've used to make that thing. For example: you make a map, and compile it. Both aas and bsp are included, but you should include too the map file. In case of textures, unless the textures were 1-layered, you should include the psd or xcf file of that texture. And ALWAYS include the license file. (COPYING, gplv2.txt, etc)
* I suggest you to grab the latest SVN build of OA (you can't play online with it, but it contains all the stuff which will be included in future versions of OA)
If you know image editing, you can help us creating some of the
missing textures/GFX replacements, or
helping the mappers with some textures/GFX they need.
If you know how to model,
mapobjects and character assitance is appreciated. If you want to rework some of the already done work, fine. The source here are the .blend files from Blender.
If you know about sound creating/editing,
then your help on for example weapon/item/ambiental sounds and voices are more than welcome.
If you're a coder, then you can help sago007 and SharpestTool with
OAX.
If you have nice mapping skills with GTKRadiant, then
of course your help is appreciated. Retexturizing existing maps on the OA SVN.
Or even better, you can throw your own suggestions/help on how to improve the existing stuff of OA, like suggestions about the maps.
Just remember to read these articles on the Wiki. Someone will post more links:
