Well, I cant read the articles because they are limited access to club members, and I understand.
I think that the extension is great. I havent had yet the neccesity to get the paid version, but I there where a "donate button" I would clikc it with pleasure.
The only thing I am missing on the basic version at least ( since I dont know how are the paid version ) is a field to fill up with a meta-description and meta-keyword on each event ( as well in category ). It will be a great additional value to your extension.
Thanks for your reply.
