[wikka-community] community Digest, Vol 38, Issue 1

[Jens Giesemann]

hi thomas,

thank you very much for your rapid and detailed information! i just have 
had a look at my providers tech limits for scripting, 13 mb ram and 90 
seconds runtime won't ever support that large uploads. m****, french 
people would say.

i like the files action very much, its great for creating ad hoc 
downloads while remote supporting via internet - but some files are a 
little bit bigger...

regards to the beautiful lake thun,

jens
