I struggle with the whole concept of joining something then not following through for whatever reason.
I truly do understand and sympathize with folks who have things happen to them through no fault of their own and afterall...this is only a hobby...lets face it, and truly not as important as health issues, family and a whole host of other things. Now with that being said....I also firmly believe that if you can't/won't follow through that you have a moral obligation to "officially" drop out and make sure that the "organizers" know so that they can make other arrangements.
Now..so you don't misunderstand...my angel did send me a package in and I loved and appreciated it, so I'm not saying or implying anything bad about my angel...I have a sweetie! :D
