@@ What is Happening? [Wrap4] Monday 8/2/16 Sydney, Australia Time 8:26pm ♪ ♫

Good evening everyone

Our great answers were delivered today by CPhill, Heureka, Solveit, rarinstraw1195, danielr_ddrp, asinus, admin and User101.

Thanks guys (and girls) :)

What is happening:

1) Our obnoxious poster from yesterday has been banned from the forum so it was very pleasant today :)

2) OUR FORUM HAS HAD A BIG UPGRADE

IT INCLUDES:

- Better profanity filter to screen out bad words.

- Pictures will be screened better to check they are appropriate.

- It is now possible to respond to a specific post within a thread.

- Non-members can no longer give points

- You can no longer give yourself points any more

- Moderators now have the ability to close threads so they cannot be added to.

THANKS MR. MASSOW

If you ask or answer an interesting question, you can private message the address to me (with copy and paste) and I will include it. Of course only members are able to do this. I quite likely will not see it if you do not show me.
