I have essential background on editing ordinary wiki - it's engine of my 
website for 5+ years - but i don't understand the link to wiki you 
mentioned. Does editing the wiki require changing something in Python 
files and then committing it to mercurial repository? In either case, 
editing the wiki is more complex than editing online spreadsheet table.
I have created a sample of google spreadsheet
There are 2 possible options:
* Allow anyone to edit (no sign-in required)
* Only people explicitly granted permission can access (google sign-up 
is required)
Which one would you prefer? Currently I set it to 1st ("allow 
everyone"). For 2nd option users with edit rights can be append recursively.
Also, which changes would you recommend to done (if you support the 
whole idea, of course)?
I have some free time to work on it along with some pypy funcs to implement.
If for some reasons you prefer another person to be owner of the google 
/ another engine table like this - no problem, let the person create 
another table and (if required) copy-paste some data from the table I've 

BTW, I have registered in bugs.pypy.org, but confirmation email hasn't 
been arrived for several hours, and re-registration doesn't help.
Let me inform you about a couple of bugs I found recently:

 >>> np.array(1).reshape(1,1)
 >>>> np.array(1).reshape(1,1)
RPython traceback:
   File "interpreter_gateway.c", line 554, in BuiltinCode_funcrun_obj
   File "implement_22.c", line 26204, in 
   File "module_micronumpy_interp_numarray.c", line 51133, in 
Fatal RPython error: NotImplementedError

 >>> np.array([1,2,3],'float')
array([ 1.,  2.,  3.])

 >>>> np.array([1,2,3],'float')
Traceback (most recent call last):
   File "<console>", line 1, in <module>
TypeError: data type not understood

(without quotes it works fine)
