Hi Harold,
you don't need to be an Elisp guru to maintain ox-taskjuggler.el, you
need to have some time to receive and review patches that may be sent
to you, and perhaps to fix some bugs.
Of course, this is your decision.
For the patches, can you simply send me the ox-taskjuggler.el file
_after_ your modifications (i.e. the latest correct version)? I will
replay the changes and apply them.
Thank you!
