I confirm that the community looks very dynamic and really want to  
produce a software for a large spectrum of researchers.
They seem to have these critical weight which permits to convince  
people using our stuff.

I have not a lot of background on the development of computer algebra  
system and I was not there at the beginning of
the project MuPAD-Combinat but my feeling is that it can be a good  
idea to switch and try to catch the train.

No problem for me and I am learning python since 2 months.

I can participate to the porting of the Symmetric Functions part with  
Mike Hansen and the stuff around ModuleWithSeveralBases.

Mike has already done a good job !

I plan to work deeper on symmetric functions with Mike Hansen during  
the workshop at MSRI

I think k-Schur functions can be almost done at MSRI with Mike.
