Good to see you're staying! Thank you for your compliment.
I'm unsure of what you had problems with in posting, let us know and someone will be able to explain it.
{There are two ways to reply to a post, like yours above: one is to use the box under the last post "Quick Reply" and the other way is to click on Reply in the upper right corner of the post. The latter way is best if the thread (all the posts under the same Main line) has a few different ideas going, you can click on the Reply tab on the post of the member you wish to directly respond to. The post still ends up at the end of the thread, but it will have the other member's s/n there. Always click on Continue when you're all done replying.)
You know how to make a new post, you just did it FINE! If you wish to post in another area, Click on Main Index, then click on the line of the forum you wish to post in... you can read the other's threads, or like here, create your own. Use the Index within the forum to see a list of all the threads available.
OH! I just remembered... there are different ways to view and I don't know which way a new member automatically comes into psychcentral set up (default) but I think it's the way I just said. (You can change things for your personal stuff by going to MY PROFILE above, and then EDIT preferences ..3 areas there. SIGH DocJohn has SOOOO much for us to play with here LOL)
PMs are another matter. Private messages are different in chat and in the main forum page area. Let me know if you have questions, OK?
Again, welcome!
