Would it be possible to add a function to hide threads? Many other forums have this feature, and I find it quite useful.

There is an extremely high likelihood that this exchange is being run for the purpose of stealing users' Bitcoin. I just tried to process a withdrawal of .001 BTC, and it went through. Once I tried processing a withdrawal for .252 BTC, it gave me a nonexistent hash and the funds vanished from my account. A friend of mine is out just under 1 BTC because the transaction is stuck on pending. Don't lose your BTC, use another exchange.
