It is easy to navigate, and has quite a bit of friendly advice. Definitely worth a visit. This concentrates more on investing. You can find analysts comments, and even a chat facility. If you lack imagination, you can visit their idea page.
Help is plentiful.
Another good site. Good quoting facilities, plenty of news and research about a company. You can store your portfolio here and automatically get prices and news for those holdings. I like the way they give you these extra tools by calling in the experts. There are plenty of screening tools to find investments which fit your requirements.
