This is a repost of a thread I started on another forum. This is one of two threads I'm reposting here. I have a feeling they should be posted in the "Edit" forums, but I'm not entirely sure they belong there.
This list has not been updated in over two years so many of the links may not work. I cannot be arsed to bother to find which ones do and do not work.
If you find a non-working link, please make a post and I'll update the thread.
If you have anything to add to the top thread, or if you want to make additional changes, post here, send me a PM, or contact me on IRC.
