Welcome to the community! Members of the community are extremely helpful, and there is information throughout the site on just about every issue you could imagine. Make sure you read ShadowSonic2's Wiihacks Ultimate Index. Here are a few things to help you get going:
1) Read the Rules of the site. They are important and there are consequences to ignoring the rules, not that you would do anything like that.
2) Read the Tutorials and Guides.
3) SEARCH for questions you may have before starting a new thread. If you would like to narrow your search, choose the option on the search page that says "Search Titles Only."
4) The advice on this site is all free, but it does cost money to operate. If you're able it would be greatly appreciated if you DONATE.
It is NOT advised that you update to system menu 4.2 at the moment. Although it can still be modded, it's only reason for existing was to eliminate the homebrew channel.
If you have not softmodded yet, there's an excellent guide by dogeggs for system menu 3.1-4.1 FOUND HERE
And a wonderful guide by messie for system menu 4.2 FOUND HERE
Any other problems can usually easily be found by searching.
