Subtle changes, bugs and feedback

I have been having a variation of this^

everytime i post recently (from home I think) i click submit. then receive the "this forum requires you to wait before posting message" or something like it and then it looks like I havent posted it as my message is still in the typyinnyboxythingy. so i submit again. lo and behold there a duplicate which i then have to sort out.

This. Something going funny somewhere.
