Jun and Simon,
I did mean what I wrote: it is maybe possible that my poor knowledge of your language prevented me from clearly expressing my thoughts.
I retry with different words:
1) Simon says it is easy to contribute.
2) Torben Brosten suggests that maybe it is not so easy...
3) I'm a beginner, not yet able to install plain OACS 4.5, despite my many efforts.
4) People writes about testing on hub.org: something unknown to me. This increases my fear not to be able...
5) Still, I would like to contribute.
6) Thus, Simon, please add me to the list.
As you see, no strong words; if any, just something agaist me: fearing to be a burden for the community instead of bringing some help.
