I've taken over the maintenance of Spreadsheet::ParseExcel from Gabor Szabo.
Initially I plan to clean up the documentation, add more working examples and deal with the more egregious bugs. I may try to clean up and document the internals as well so that someone else can take over maintenance and so that patches are more consistent. It will also give me a chance to get ParseExcel and WriteExcel working better together.
Anyway, I've set up a Google Group for discussions relating to the module: Spreadsheet::ParseExcel Group.
Feel free to join, post, chat if you are interested.
Update: I've added a roadmap for Spreadsheet::ParseExcel.
