5 posts/4 hours is reasonable. 5 posts is easy, and you really should spend at least 4 hours reading through the forums to educate yourself. Otherwise your posts will probably be misinformed or just repeating topics that have already been covered 10 times over. Besides, if you look around, the newbie section actually has a lot of interesting discussion going on.

4 Hours is nothing, just reading on setting up Linuxcoin with SmartCoin took that, going back and forth seeing my setup wouldn't work and finally did get it working. Just add trying to find out the best settings for Phoenix and phatk took a good 30 minutes for my cards. Also you can read whats for sale and some of the services in the marketplace for 30 minutes.
