WHAT'S WRONG?

i just took an opps then i write and write and write then when i want to submit, i was met with "All of the available posts for that opportunity have already been taken". WTH????????? wasted my time writing only, i am sure i reserved the opps and i typed in the captcha and everything. so what's going on? not that it is a big amount, but then wasted my time and energy writing and thinking mah.. siann sian siannn...

ok, enough, i am going back to sleep now. morning!!
