Recently I found an interesting and useful site for Linux Howtos - http://www.howtoforge.org.

HowToForge.org is a databank of articles that are written from linux-to-linux users. The howtos are classified in 16 groups including Apache, MySQL, PHP, Sendmail, Samba, and some general topics like Security, Linux, Backup, DNS.

Everyone can register an author account and write a story. A story is similar to a newspaper article. If stories are moderated, the post will be submitted to the attention of other users and be queued in the submission queue. Users and moderators vote on the posts they like or dislike, promoting or demoting them. When a post gets above a certain threshold it automatically gets promoted to the front page.

So, if you are a Linux user and want to share something with other users, go on !
