Forum Rules: Marking your Thread as Solved
Thanks to DonCash for this contribution. He will also be one of the moderators on the forum in a few minutes
By the way, i created a new subforum called "Forum Guides" under "Forum Lobby" forum. We can post our guides to users to this forum but please make sure the guides has a clear purpose and they are high quality guides. It is best to discuss content of them with other members here before posting it to the "Forum Guides" forum.
For example, as a starting point, if anyone want to develop a guide for java newbies, i will be happy to publish it on "Forum Guides" forum once it is ready to publish.
