Thanks Kyatric but this is what I wanted to avoid.
I think that on the "upload game" page there should be a link or even the list itself with the supported plugins.
Currently the list = Built-in plugins and behaviors - (webStorage + Ajax + Browser + Facebook)
What I tried to say is that I don't have a clue what are the built-in plugins and behaviors. To check this I would need to check the ones I used and for each one to go over the 3rd party list.
If we had a link over there (or the list itself) of supported plugins/behaviors the task would have been simplified for users who wish to upload their game/s.
As time passes I'm sure the arcade will support additional 3rd party plugins/behavior. In the current status the formula will be even more complex = built-in - X - Y (beside Z, F and G)
Hope this makes sense.
