I have tried three times in the last thirty minutes to respond to a note and each time I finish my response and try to submit my note I get the error message " Invalid Session". I am very frustrated with this and would like to know what I could possibly be doing to cause this to happen.

Hello Kay,
You are not going crazy, well maybe the Invalid Sessions were driving you crazy . I had the same problem and have complained to the top many times over the past year .

The problem was the version of the forum software they were running. Finally they have upgraded the software and the Invalid Session messages should be gone forever!!!
