i think alot of internet servers have been having problems lately- i know my Verizon has been having issues- i think it is more problems with the internet connection & your computer- not the board itself.
sometimes i will post 2 or 3 times then get *bumped* and have to sign back in- i've started doing a quick copy of my posts before hitting the post reply button- so if it doesn't go i can just do a paste instead of starting over.
