I would like to thank the developer for the Appointments+ plugin. I have built an appointments page for my client with it. Well done.
Here is a list with suggestions that came up while I was working with Appointments+. Keep up the good work!
Edit: The attachment is missing because .rtfd is a "denied extension". Sigh. Send me an email at mdlust (followed by at sign and xs4all.nl) and I'll mail it to you.
