No need to apologize, I'm sure you're a busy person! :-)
I'm rather new to open source in general and jDownloads in particular. Is there a path for a developer (me) to create a plug-in for jDownloads or is this something that only you do?
By the way, I just downloaded "com_jdownloads_22.214.171.124_beta_for_joomla_3.1.zip". Can I just install this over my existing version from the Joomla Extension Manager, or do I need to update manually (copy the files via FTP into the correct folders)?
