I am not sure how many folks already know this, but I just found out when I tried to post! After I spent time writing a response I received the message "This post is over 402 days old so you can not reply"
So two things I want to say:
1) If you can't reply to a post it should say that so you don't waist time
trying to reply!
2) If you post something and really want to hear all responses no mater how old your post is you need to go in every now and then and post something to keep it reply able!
Maybe one of the Admins could tell us how long a post can go without reply's before it is un postable! Just my 2 cents worth
