I purchased this extension and it installed easy enough using the readme.txt file that was available but there is little to no other documentation, such as a user manual or online help. I am using this for a church calendar and need to post recurring events. These events are worship services and obviously do not require registration. I finally figured how to control that but the biggest issue is I cannot set just a start date and time and when i edit the parent item it does not change so it has been quite a frustrating 3 hours for, what should have taken 3 seconds to fix. Anyway I think it could be a good extension but the bugs are not worked out. If I am doing something wrong then it would help to have supporting documentation but can't find it.
The tutorial documents are available on my site under Tutorial documents(I don't include it in the readme file). There are two tutorials: one for installing the extension and one for using the extension.
In case you have any questions, feel free to contact me via Skype, YM, MSN or Gtalk so that I can answer any of your questions.
