why is this obvious? The OP simply asked if other PerlMonks had played with the technology.

Strictly speaking you're perfectly right! It all boils down to about how strict you're willing to be in interpreting his request. Indeed if he's strictly interested in other "monks" playing with that technology, then my remark is likely to be at best marginally relevant for there's no a priori guarantee that the project admin is a member of PM nor that he even knows any that are also interested in the project itself.

OTOH it seems to me that, in a more reasonable way to interpret his request, he'd be rather interested in other people playing with that technology. In fact he also wrote:

I am a Perl newb, with a Series80 phone, Perl installed and working. Am keen to throw some time at making it do something useful/fun, so a curious to see what others might have tried.

Now, pointing him to the project admin should be somewhat obvious, since he's very likely to be interested in... ehm... the project and to know other who are.
