Use the forum, there is a whole index of sections you can use. But this one isn't the right place to ask questions, unless they are directly about the wiki!
Feel free to post notes about broken links in wiki entries, or suggestions for wikis, or wiki starter posts that other people can add to.
But if you want careers advice, post in the appropriate part of the forum, so that you get some answers and I don't have to keep moving posts to the right place.
Wise men talk because they have something to say, fools because they have to say something - Plato
The fool thinks himself to be wise, but the wise man knows himself to be a fool - Shakespeare
