Bought JTAG calendar the other day and found out the installation is very easy. I wanted to adapt the appearance to suit my website so I joined the JTAG calendar forum and asked a question. Within a few hours I got a reply (also via mail) and got great support. Even when I did not understand the provided instructions the first time, the JTAG support team was very patient with me and helped me till all changes I wanted to make were done. I actually found out that the JTAG Calendar extension is highly customizable to suit one’s individual need. Worth every dollar!
