How to change my picture (gravatar) and what is a gravatar?

The picture that appears on the users profiles is called a gravatar (which means globally recognized avatar).

Here is how it works: a cryptographic key (unbreakable code) is calculated from your email address. You upload your picture (or your favorite alter ego image) the website from where we later retreive your image using the key.

This way all the websites you trust can show your image next to your posts and your email address remains private.

Please personalize your account with an image - just register at (just please be sure to use the same email address that you used to register with us). A default image that looks like a kitchen tile is generated automatically.

What should I avoid in my answers?

Composites.GURU Q&A Forum is a question and answer site - it is not a discussion group. Please avoid holding debates in your answers as they tend to dilute the essense of questions and answers. For the brief discussions please use commenting facility.

Who moderates this community?

The short answer is: you. This website is moderated by the users. The karma system allows users to earn rights to perform a variety of moderation tasks

How does the karma system work?

When a question or answer is upvoted, the user who posted them will gain some points, which are called "karma points". These points serve as a rough measure of the community trust to him/her. Various moderation tasks are gradually assigned to the users based on those points.

For example, if you ask an interesting question or give a helpful answer, your input will be up-voted. On the other hand if the answer is misleading - it will be down-voted. Each vote in favor will generate 10 points, each vote against will subtract 10 points. There is a limit of 200 points that can be accumulated for a question or answer per day. The table below explains reputation point requirements for each type of moderation task.

How can I post a link if I don't have any karma yet?

You can post a link to things without karma as long as it does not get rendered as a link. If you put it inside of a block quote it will not get rendered. The karma lmits for various actions are there to prevent spammers from creating a lot of content.

To register, do I need to create new password?

No, you don't have to. You can login through any service that supports OpenID, e.g. Google, Yahoo, AOL, etc. "Login now!" ยป
