I agree, take the high road. There is always some people who think they know it all and are better than anyone else. Let them put their money where their mouth is. People will see in time all that you did do. And although they (the buggers) will never admit itto it, they will also see how much "behind the scenes" work had been done by you. I had people say that "we are going to do a lot mor FUN things"" we are going to do .... this, we are going to do that.." yeah yeah, yeah. blah, blah, blah. Guess what? I haven't seen anything different and new PLUS the organization has little or no communication with the general members since the newsletters that were started a couple years back have seem to disappeared and the only way you find anything out is if you go to a meeting. We all know that very few people attend the meetings and it is our obligation to get the "news out". It seems they can not keep up with the "behind the scenes" stuff or maybe it is more than they can handle.
Give them the information and let them take it from there. They may choose to not even read it thinking they "know it all", but SMART people learn from others and read over notes to see the organization and flow of an event - DUMB people do not.
(sorry could not resist that one)
You will see, in a year and so will everyone else. So Hold your head high, follow the high road, resist the urge to badmouth to anyone... (you all know the grapevines at school). Another thing to do, is kill em with kindness and great big smiles!
