Suppose you've read one of the resources above and ran into a problem. Now what should you do?

IRC (Internet Relay Chat): Internet Relay Chat is probably the fastest way to receive answers to most common beginner questions. Please visit the link to learn more about it, and see where it is best to ask, what to avoid doing and what to expect.
Mailing Lists: Mailing lists allow you to ask questions by E-mail and also learn from similar discussions. They are the best solution for more obscure questions, or if you're not short on time and want less interactive, but more in-depth discussions.
Web Forums: Web forums are similar to mailing lists, but all interaction is done through a web-browser, and one can use web feeds to monitor them. We have concentrated a selection of Vim-related web forums on the Web Forums page.

General Reference Resources: Reference resources that did not fit elsewhere, including those from the core Perl 5 documentation.
Wikis: Wikis are dynamically editable web-sites that allow for collaborative editing of useful information. Vim has several wikis with active contributors, that help write useful knowledge.
Blogs: Blogs, Weblogs or Online Journals where people write about Vim.
